Owner Operator Costs: Complete Expense Breakdown
Every expense you will face as an owner operator -- per mile, per month, and per year. Real benchmarks by equipment type with a monthly budget template.
Why Knowing Your Costs Matters
If you cannot tell someone your exact cost per mile, you are guessing at profitability every time you book a load. That is not a business -- it is gambling. A load that pays $2.50 per mile looks great until you realize your operating cost is $1.95 per mile and the 800-mile deadhead to get to the shipper pushes your effective rate below your break-even point.
This guide breaks down every expense an owner operator faces -- fixed, variable, and the ones most people forget -- with real dollar amounts per mile, per month, and per year1. Whether you are planning your launch or trying to figure out where your money is going after six months on the road, these benchmarks give you a framework to measure your operation against.
If you are still in the planning stage, our starting a trucking business guide covers the full launch process step by step. This guide focuses specifically on ongoing costs once you are operating.
Fixed Costs: What You Pay Regardless of Miles
Fixed costs hit your bank account every month whether you run 10,000 miles or zero. Understanding and minimizing fixed costs is critical because they determine your baseline overhead -- the amount you must earn before you make a single dollar of profit.
Truck Payment
For most owner operators, the truck payment is the largest or second-largest fixed expense.
| Scenario | Monthly Payment |
|---|---|
| Used truck ($60,000, bank loan at 8.5%, 60 months, 20% down) | ~$990 |
| Used truck ($80,000, bank loan at 8.5%, 60 months, 20% down) | ~$1,315 |
| Used truck ($70,000, equipment finance at 12%, 48 months, 15% down) | ~$1,570 |
| Lease-purchase program (typical carrier) | $2,400-$3,200 |
| Truck paid off | $0 |
Operators with paid-off trucks have an enormous competitive advantage. Their break-even cost per mile drops by $0.10-$0.15, which means they can accept loads that would be unprofitable for operators carrying a $1,500 monthly truck note. If accelerating your payoff is feasible, every extra dollar toward principal saves you multiples in interest over time.
Insurance
Insurance is consistently the most painful fixed cost, especially in years one and two.
| Coverage | Annual Cost (New Authority) | Monthly | Per Mile (10K mi/mo) |
|---|---|---|---|
| Primary liability ($1M)36 | $8,000-$14,000 | $667-$1,167 | $0.07-$0.12 |
| Cargo ($100K) | $1,200-$2,400 | $100-$200 | $0.01-$0.02 |
| Physical damage | $2,000-$5,000 | $167-$417 | $0.02-$0.04 |
| Occupational accident | $1,800-$3,600 | $150-$300 | $0.02-$0.03 |
| Total | $13,000-$25,000 | $1,083-$2,083 | $0.11-$0.21 |
Here is the critical context: insurance premiums drop significantly as you build a clean safety record. A carrier paying $18,000 per year in year one might pay $13,000 by year three -- a $5,000 annual savings that goes straight to the bottom line.
Shopping your insurance at every annual renewal is not optional. Get at least three quotes from agents who specialize in trucking. Rates vary by thousands for identical coverage because different underwriters weigh risk factors differently. Compare insurance providers to find specialized trucking agents who work with your profile.
ELD Subscription
If you chose a subscription-based ELD, this is a small but recurring monthly cost.
- Subscription ELD (Motive, Samsara): $30-$45/month ($360-$540/year)
- No-monthly-fee ELD: $0/month after initial hardware purchase
Permits and Registrations
| Item | Annual Cost |
|---|---|
| UCR registration7 | $76 |
| IRP renewal (apportioned plates) | $1,500-$2,500 |
| IFTA decals | $5-$10 |
| Heavy Vehicle Use Tax (Form 2290) | $550 for trucks 55,000+ lbs GVW8 |
| Drug and alcohol consortium | $75-$200 |
| Business/state permits (varies) | $0-$300 |
| Total | $2,200-$3,600 |
Spread across 12 months, permits and registrations cost about $185-$300 per month.
Accounting and Administrative
| Item | Monthly Cost |
|---|---|
| Accounting software (QuickBooks, Wave) | $0-$30 |
| Bookkeeping service (if outsourced) | $100-$300 |
| Phone and data plan | $75-$150 |
| Load board subscription (DAT, Truckstop) | $0-$175 |
| LLC annual fee (state-dependent) | $0-$67/month (avg) |
| Total | $175-$720 |
Total Fixed Costs Summary
| Category | Monthly Range | Annual Range |
|---|---|---|
| Truck payment | $0-$1,570 | $0-$18,840 |
| Insurance | $1,083-$2,083 | $13,000-$25,000 |
| ELD subscription | $0-$45 | $0-$540 |
| Permits and registrations | $185-$300 | $2,200-$3,600 |
| Accounting and admin | $175-$720 | $2,100-$8,640 |
| Total Fixed | $1,443-$4,718 | $17,300-$56,620 |
For an owner operator with a truck payment and full insurance, fixed costs typically fall in the $2,500-$3,800 per month range. That is the nut you have to crack before variable costs and profit enter the picture.
Variable Costs: What Changes with Miles
Variable costs scale with how much you drive. The more miles you run, the more you spend on fuel, maintenance, tires, and road expenses. Understanding your variable cost per mile is essential for evaluating whether a specific load is profitable.
Fuel
Fuel is your single largest variable expense and the one with the most fluctuation2. Diesel prices swing $0.50-$1.00 per gallon over the course of a year, and that swing translates directly to your bottom line.
Per-mile fuel cost formula:
Fuel Cost Per Mile = Price Per Gallon / Miles Per Gallon
| Diesel Price | 5.5 MPG | 6.0 MPG | 6.5 MPG | 7.0 MPG |
|---|---|---|---|---|
| $3.50/gal | $0.64 | $0.58 | $0.54 | $0.50 |
| $3.75/gal | $0.68 | $0.63 | $0.58 | $0.54 |
| $4.00/gal | $0.73 | $0.67 | $0.62 | $0.57 |
| $4.25/gal | $0.77 | $0.71 | $0.65 | $0.61 |
| $4.50/gal | $0.82 | $0.75 | $0.69 | $0.64 |
At 10,000 miles per month with $4.00 diesel and 6.5 MPG, fuel costs about $6,150 per month. Every 0.5 MPG improvement in fuel efficiency saves roughly $400-$500 per month.
How to reduce fuel costs:
- Fuel cards. A good fuel card saves $0.20-$0.60 per gallon at participating truck stops. At 1,200 gallons per month, that is $240-$720 in monthly savings. Compare fuel cards to see current discount levels by network.
- Speed management. Dropping from 68 mph to 63 mph can improve fuel economy by 0.3-0.5 MPG. On 10,000 miles, that saves $300-$500 per month in fuel.
- Route planning. Avoid mountainous routes when possible. Plan fuel stops at the cheapest locations on your lane. Apps like GasBuddy and Trucker Path show real-time diesel prices by location.
- Tire pressure. Underinflated tires increase fuel consumption by 1-3%. Check pressure at every pre-trip inspection.
Maintenance and Repairs
Maintenance costs break into two categories: scheduled preventive maintenance (predictable) and unscheduled repairs (unpredictable but inevitable).
Scheduled maintenance costs:
| Service | Frequency | Cost Per Service |
|---|---|---|
| Oil and filter change | Every 15,000-25,000 miles | $250-$400 |
| Fuel filter replacement | Every 20,000-30,000 miles | $75-$150 |
| Air filter replacement | Every 30,000-50,000 miles | $50-$100 |
| Coolant flush | Every 300,000-500,000 miles | $150-$300 |
| DPF cleaning | Every 200,000-300,000 miles | $300-$600 |
| Brake adjustment/inspection | Every 25,000-30,000 miles | $75-$200 |
| Grease/lubrication | Every oil change | $50-$100 |
| Annual DOT inspection | Once per year | $50-$150 |
Unscheduled repairs are harder to predict but easier to budget for if you think in per-mile terms. Common unscheduled expenses include brake replacements ($800-$2,000 per axle), alternator/starter replacement ($500-$1,200), A/C compressor ($800-$1,500), DPF/DEF system repairs ($2,000-$8,000), and turbo replacement ($2,000-$4,000).
Per-mile maintenance benchmarks:
| Truck Age/Condition | Maintenance Cost Per Mile |
|---|---|
| Newer truck (under 300K miles) | $0.08-$0.12 |
| Mid-life truck (300K-600K miles) | $0.12-$0.18 |
| Older truck (600K+ miles) | $0.15-$0.25+ |
At 10,000 miles per month, maintenance runs $800-$2,500 per month depending on truck age and condition. The key is setting this money aside in a dedicated maintenance fund whether you spend it this month or not. A good month with no repairs builds the cushion for the month when you need a $3,000 brake job.
Tires
Tires deserve their own line item because the cost is substantial and occurs in lumps. A full set of drive and steer tires runs $1,800-$4,000, and a set typically lasts 150,000-250,000 miles depending on driving style, alignment, and tire quality.
| Tire Position | Cost Per Tire | Quantity | Total |
|---|---|---|---|
| Steer tires | $350-$550 each | 2 | $700-$1,100 |
| Drive tires | $250-$400 each | 8 | $2,000-$3,200 |
| Full set | 10 | $2,700-$4,300 |
Spread over 200,000 miles, that works out to about $0.01-$0.02 per mile. But the expense does not arrive per mile -- it arrives as a $2,700-$4,300 bill every 12-18 months. Budget for it monthly so the bill does not catch you off guard.
Do not forget retreads. Quality retreads cost 40-60% less than new tires and are perfectly acceptable (and common) for drive positions. Most fleet operators run retreads on drives and new tires on steers. Steer tires should always be new -- do not run retreads on steer axles.
Tolls
Toll costs vary enormously by region. Running lanes through the Northeast corridor (I-95, New Jersey Turnpike, George Washington Bridge) can cost $50-$100+ per trip in tolls. Running through the Midwest or Southeast, you might pay close to zero.
Per-mile toll benchmark: $0.02-$0.06 depending on operating region.
A pre-paid toll transponder (E-ZPass, TollTag, SunPass) saves 10-30% on toll costs in most states and eliminates the hassle of carrying cash through toll plazas.
DEF Fluid (Diesel Exhaust Fluid)
Every modern diesel truck with an SCR (Selective Catalytic Reduction) system uses DEF fluid. Consumption runs about 2-3% of fuel usage, which translates to roughly 15-30 gallons per month.
- Cost at the pump: $2.50-$3.50/gallon
- Cost in bulk (2.5-gallon jugs): $3.00-$5.00/gallon
- Monthly cost: $40-$100
It is a small expense but one that catches new operators off guard because it was not part of older truck economics. Always buy DEF at the pump rather than in jugs when possible -- it is cheaper and you do not have to haul jugs around.
Lumper Fees
Lumper fees are charges for unloading freight at certain warehouses and distribution centers. They range from $50-$300 per occurrence and are most common on grocery and retail loads. Some shippers reimburse lumper fees; many do not. When evaluating a load, ask upfront whether lumper fees apply and whether they are reimbursed.
Per-mile benchmark: Varies wildly. Could be $0 if you avoid lumper-heavy freight, or $0.01-$0.04 per mile if you regularly deliver to grocery/retail warehouses.
Scales
Most states have weigh stations that require commercial vehicles to stop for weight verification. While the weigh station itself is free, scale tickets from CAT scales (used to check your own weight before hitting the road) cost $12-$15 per weigh. If you scale twice per load, that is $24-$30 per load.
Some operators also carry PrePass or Drivewyze subscriptions ($15-$30/month) that allow you to bypass many weigh stations, saving time and fuel from deceleration and acceleration.

Equipment Type Comparison: Dry Van vs. Flatbed vs. Reefer
Not all equipment types cost the same to operate. The truck that pulls your trailer is similar across types, but trailer costs, fuel consumption, and maintenance profiles differ significantly.
Dry Van
Dry van is the most common trailer type and the simplest to operate. Standard 53-foot enclosed trailers with no special equipment.
| Cost Factor | Dry Van |
|---|---|
| Trailer cost (used) | $15,000-$30,000 |
| Trailer lease | $400-$700/month |
| Extra fuel consumption | Baseline |
| Extra maintenance | Minimal -- door seals, floor repairs |
| Average rate premium vs. dry van | Baseline |
| Additional monthly cost | $400-$700 (if leasing trailer) |
Flatbed
Flatbed operations command higher rates but come with additional costs for securement equipment, tarps, and physical labor.
| Cost Factor | Flatbed |
|---|---|
| Trailer cost (used) | $15,000-$35,000 |
| Trailer lease | $400-$800/month |
| Tarps and securement equipment | $1,500-$3,000 upfront, $500-$1,000/year replacement |
| Extra fuel consumption | Similar to dry van (slightly better aerodynamics when empty) |
| Physical wear and injury risk | Higher -- loading/unloading, tarping in weather |
| Average rate premium vs. dry van | +$0.15-$0.40/mile |
| Additional monthly cost vs. dry van | +$100-$300 |
Flatbed can be more profitable because rates are higher and there is less competition (fewer drivers want to tarp loads in January rain). The trade-off is harder physical work and more time spent securing loads.
Reefer (Refrigerated)
Reefer operations have the highest operating costs but also command premium rates for temperature-sensitive freight.
| Cost Factor | Reefer |
|---|---|
| Trailer cost (used) | $25,000-$55,000 |
| Trailer lease | $800-$1,400/month |
| Reefer fuel consumption | 0.5-1.0 gallon/hour of reefer operation |
| Reefer maintenance | $2,000-$5,000/year (unit servicing, refrigerant, sensors) |
| Extra insurance cost | +$1,000-$2,500/year for cargo spoilage coverage |
| Average rate premium vs. dry van | +$0.20-$0.50/mile |
| Additional monthly cost vs. dry van | +$500-$1,200 |
Reefer fuel costs are often overlooked by new operators. The refrigeration unit burns 0.5-1.0 gallon of diesel per hour, running continuously during transit. On a 24-hour loaded run, that is an extra 12-24 gallons of fuel -- $42-$96 at $3.50/gallon -- on top of the truck's fuel consumption.
Side-by-Side Monthly Budget Comparison
| Expense | Dry Van | Flatbed | Reefer |
|---|---|---|---|
| Truck payment | $1,200 | $1,200 | $1,200 |
| Trailer lease | $550 | $600 | $1,100 |
| Insurance | $1,500 | $1,500 | $1,700 |
| Fuel (truck) | $5,500 | $5,500 | $5,500 |
| Fuel (reefer unit) | -- | -- | $600 |
| Maintenance (truck + trailer) | $1,300 | $1,400 | $1,700 |
| Tarps/securement | -- | $100 | -- |
| Permits/admin/ELD | $550 | $550 | $550 |
| Tolls/scales/DEF | $520 | $520 | $520 |
| Total Monthly Cost | $11,120 | $11,370 | $12,870 |
| Average gross revenue | $18,000 | $20,000 | $21,000 |
| Net before taxes/living | $6,880 | $8,630 | $8,130 |
These numbers illustrate why flatbed can be the most profitable equipment type for owner operators willing to do the physical work. Higher rates plus only marginally higher costs equals the best net margin. Reefer has the highest gross revenue but the additional fuel and maintenance costs eat into the advantage.

Annual Cost Summary
Here is the annual view for a typical single-truck dry van owner operator:
| Category | Low Estimate | Mid Estimate | High Estimate |
|---|---|---|---|
| Truck payment | $11,880 | $15,000 | $18,840 |
| Insurance | $13,000 | $17,000 | $25,000 |
| Fuel | $48,000 | $60,000 | $78,000 |
| Maintenance and repairs | $9,600 | $15,000 | $24,000 |
| Tires | $1,500 | $2,500 | $4,000 |
| Trailer lease | $4,800 | $6,600 | $9,600 |
| Permits and registrations | $2,200 | $2,800 | $3,600 |
| Admin/ELD/load board | $2,100 | $4,200 | $8,640 |
| Tolls/scales/DEF | $2,000 | $4,500 | $8,000 |
| Factoring fees | $2,400 | $5,400 | $9,600 |
| Total Annual Expenses | $97,480 | $133,000 | $189,280 |
| Gross revenue | $180,000 | $216,000 | $264,000 |
| Net before taxes | $82,520 | $83,000 | $74,720 |
| Self-employment + income tax | $22,000 | $24,000 | $22,000 |
| Take-home income | $60,520 | $59,000 | $52,720 |
Notice something interesting in this table: the high-estimate operator grosses $264,000 but takes home less than the low-estimate operator who grosses $180,000. That is because the high-estimate scenario involves a newer, more expensive truck, premium insurance, higher fuel consumption, and a more expensive operating profile. Gross revenue is vanity. Net income is sanity. What matters is what you keep, not what you gross.
What Most Truckers Forget to Budget For
After 25 years of working with owner operators, I can tell you exactly which expenses catch people off guard. These are the costs that do not show up in the first month or two but hit hard when they arrive.
Quarterly Estimated Taxes
As a self-employed business owner, the IRS expects you to pay taxes quarterly -- not once a year in April89. If you net $70,000, you owe roughly $10,700 in self-employment tax plus income tax on top of that. Divide by four, and that is $5,000-$7,000 due every quarter (April 15, June 15, September 15, January 15).
Miss these payments and you face underpayment penalties. Worse, many operators who do not set money aside quarterly get hit with a $15,000-$25,000 tax bill in April that they cannot pay. Set aside 25-30% of net income every month in a separate savings account and do not touch it. For a detailed look at deductions that can reduce your tax burden, see our guide on trucking tax deductions.
Tire Replacement Fund
Tires do not wear out monthly, but they do wear out. A full set of steer and drive tires costs $2,700-$4,300 and lasts 150,000-250,000 miles. If you run 10,000 miles per month, that set needs replacing every 15-25 months. Set aside $150-$300 per month so the money is there when you need it.
DEF Fluid
Modern trucks consume DEF at roughly 2-3% of fuel usage. It is a small line item ($40-$100/month) but one that did not exist for operators running pre-2010 trucks. Running out of DEF triggers a derate that limits your truck to 5 mph -- not a situation you want on a loaded run.
Annual DOT Inspection
Every commercial vehicle must pass an annual DOT inspection. The inspection itself costs $50-$150, but the real cost is any repairs needed to pass. Brakes, lights, tires, suspension components, and air systems all get scrutinized. Budget $500-$1,500 for the inspection plus any required repairs, and schedule it proactively rather than waiting for a roadside inspection to flag issues.
Deadhead Miles
Empty miles are real miles with real costs -- fuel, wear, driver time -- and zero revenue. Industry-wide, deadhead rates average 10-15% of total miles. That means for every 10,000 revenue miles, you are driving 1,000-1,500 miles empty. Those deadhead miles cost $0.65-$1.00 each in fuel and wear but generate nothing. Minimizing deadhead is one of the most impactful things you can do for profitability.
Breakdown Towing
A single tow can cost $300-$1,500 depending on distance and whether you need a heavy-duty wrecker. Breakdowns that happen at 2:00 AM on a Sunday on a rural stretch of I-40 cost more than breakdowns at a truck stop in Dallas. Budget for at least one tow per year.
License and Registration Renewals
IRP renewal, UCR annual registration, IFTA decal renewal, CDL renewal, medical card renewal, drug consortium annual fee -- these are all annual costs that arrive at different times throughout the year. Put them on a calendar so none of them sneak up on you.
How to Track and Reduce Costs
Knowing what your costs should be is step one. Tracking what they actually are is step two. Reducing them is step three.
Tracking Systems
Minimum viable tracking: A spreadsheet with columns for date, category, amount, and miles. Update it daily. At the end of each month, total each category and divide by miles driven to get your per-mile cost by category. This takes 10 minutes a day and gives you 90% of the insight you need.
Better tracking: Accounting software like QuickBooks Self-Employed ($15/month) or a trucking-specific platform like ATBS ($50-$100/month). These categorize expenses automatically from bank and credit card feeds, generate profit and loss statements, and calculate per-mile costs. They also simplify tax filing by tracking deductible expenses throughout the year.
Best tracking: Combine accounting software with your ELD mileage data and fuel card reports. This gives you automated, accurate tracking of revenue miles, deadhead miles, fuel cost per mile, and total cost per mile with almost no manual entry.
Cost Reduction Priorities
Focus on the biggest line items first. Saving 10% on a $5,500 monthly fuel bill ($550) has more impact than saving 50% on a $70 monthly DEF bill ($35).
- Fuel: Use a fuel card, manage speed, plan routes for cheaper fuel stops, maintain tire pressure. Potential savings: $200-$700/month.
- Insurance: Re-shop at every annual renewal with specialized trucking agents. Potential savings: $200-$500/month by year 2-3.
- Deadhead: Plan round-trip lanes, build relationships with brokers who can cover backhauls, stay flexible on pickup timing. Reducing deadhead from 15% to 10% adds $500-$800/month in effective revenue.
- Maintenance: Stay on schedule with preventive maintenance. A $300 oil change prevents a $15,000 engine failure. Potential savings: Incalculable, but the math is obvious.
- Factoring: As you build cash reserves, you can factor fewer loads and keep more of your revenue. Moving from factoring 100% of loads to 50% saves $200-$400/month.
Frequently Asked Questions
The FAQ section is built into the frontmatter above for structured data. Here is additional context on commonly asked questions from owner operators.
How Do I Calculate My Break-Even Rate?
Add up your total monthly expenses (fixed plus variable, including a reasonable estimate for taxes). Divide by your expected revenue miles for the month (total miles minus deadhead). That gives you your break-even rate per mile. If your total expenses are $11,000 and you run 8,500 revenue miles, your break-even rate is $1.29 per mile.

Are Owner Operator Costs Tax Deductible?
Almost all business operating expenses are tax deductible, including fuel, maintenance, insurance, truck payments (depreciation and interest), tolls, per diem meals, phone bills, and ELD subscriptions. The per diem deduction alone -- $69 per day for full days away from home in 20265 -- can reduce your taxable income by $15,000-$20,000 per year if you are on the road 250+ days.
How Much Should I Save for Emergencies?
Keep a minimum of $5,000-$10,000 in an emergency fund separate from your operating accounts. This covers a major breakdown, a tow, a missed load, or a week off the road for illness. Operators with less than $3,000 in reserves are one bad week away from a financial crisis.
Next Steps
Now that you understand the full cost picture, put it to work:
- Calculate your actual cost per mile. Use our cost per mile calculator to input your real numbers and see exactly where you stand versus industry benchmarks.
- Build your monthly budget. Take the template above and fill in your actual numbers. Track against it every month.
- Identify your biggest cost reduction opportunity. Is it fuel? Insurance? Deadhead? Pick the biggest one and take action this month.
- Set aside tax reserves. Open a separate savings account today and start moving 25-30% of net income into it before you spend a dollar on anything else.
- Review quarterly. Costs change -- fuel prices swing, maintenance needs evolve, and insurance renewals offer savings opportunities. A quarterly review of your budget versus actuals keeps you in control.
The owner operators who succeed long-term are not always the ones who gross the most. They are the ones who know their costs, manage their expenses, and make load decisions based on data rather than gut feeling. This breakdown gives you the framework. The discipline is up to you.
Frequently Asked Questions
- What is the average cost per mile for an owner operator?
- Total operating cost per mile for a single-truck owner operator typically falls between $1.50 and $2.10 depending on equipment type, truck age, fuel prices, and insurance rates. Dry van operations average around $1.60-$1.85 per mile. Reefer operations run $1.75-$2.10 due to higher fuel consumption and equipment costs. These figures include all fixed and variable expenses but do not include the driver's take-home pay.
- How much does an owner operator spend on fuel per month?
- At current diesel prices, a single-truck owner operator running 8,000-10,000 miles per month typically spends $4,000-$6,500 on fuel. The exact amount depends on fuel prices in your operating region, your truck's fuel efficiency (5.5-7.5 MPG), and whether you use a fuel card for discounts. Fuel is the largest variable expense, usually accounting for 30-40% of gross revenue.
- What are the biggest hidden costs for owner operators?
- The expenses most owner operators underestimate include quarterly estimated tax payments (25-30% of net income), tire replacement ($1,800-$4,000 per set of drive and steer tires), DEF fluid ($50-$100/month), annual DOT inspection ($50-$150), lumper fees ($50-$300 per load at certain warehouses), and scale/toll costs that add up to $200-$500 per month. These hidden costs can total $15,000-$25,000 per year.
- How much does truck insurance cost for an owner operator?
- First-year insurance for a new authority owner operator typically costs $12,000-$22,000 annually for a full coverage package including primary liability, cargo, and physical damage. That works out to $1,000-$1,833 per month or approximately $0.08-$0.15 per mile. Rates decrease 15-25% after your first clean year and continue dropping for 3-5 years as you build a safety record.
- How much should an owner operator set aside for maintenance?
- Budget $0.10-$0.18 per mile for maintenance, which translates to roughly $1,000-$1,800 per month at 10,000 miles. This covers scheduled maintenance (oil changes, filters, greasing) and builds a reserve for unscheduled repairs (brakes, tires, electrical issues, emissions system problems). Older trucks with 500,000-plus miles should budget toward the higher end. Setting aside a dedicated maintenance fund prevents a single breakdown from becoming a financial crisis.
