Food Truck Equipment Master Guide (2026)

by

A food truck is a kitchen with three extra constraints

Brick-and-mortar restaurant equipment decisions are constrained by code, layout, and budget. Food truck decisions add three more: weight (axle and chassis limits), power (generator capacity and propane storage), and motion (vibration tolerance, secured equipment, road-legal exhaust). A 6-burner range that’s perfect on a stationary cookline becomes a fire hazard on a 22-ft truck if the burners aren’t secured for transit and the propane storage isn’t compliant with NFPA 58.

This pillar walks the decision tree for food truck builds — chassis size, equipment list, generator and propane sizing, and the regulatory framework that’s stricter on a moving kitchen than on a brick-and-mortar one.

Decision Question 1 — What chassis size do you need?

Food trucks divide roughly into three chassis classes:

16-foot box / step-van ($35k–$80k built) — minimum viable food truck. Single concept, narrow menu, 1–2 cook crew. Good for: coffee, tacos, sandwiches, single-protein concepts.

20-foot truck or trailer ($55k–$140k built) — operator default for most food truck concepts. Full cookline plus prep + fryer + holding. 2–3 cook crew. Good for: most multi-item concepts.

24-foot truck or trailer ($90k–$200k built) — high-volume / multi-station. 3–4 cook crew. Good for: festival circuit, catering, complex menus.

Decision rule:

If your menu has fewer than 8 items and your peak demand is under 80 orders/hour: 16-ft.

If your menu has 8–18 items and peak is 80–150 orders/hour: 20-ft.

If your menu has 18+ items or peak exceeds 150 orders/hour: 24-ft.

Decision Question 2 — Truck or trailer?

Self-propelled truck (built on a van or stepped chassis): drives itself. Costs $25k–$80k for the chassis + $40k–$120k for the build-out. Total $65k–$200k.

Towable trailer: requires a tow vehicle. Trailer cost $25k–$80k typically; chassis truck (Ford F-250 or similar) is operator’s existing or $40k–$80k additional. Trailer total $50k–$160k.

Trade-offs:

Truck: more mobile (no separate tow vehicle), but chassis ages and full unit replacement is one decision.

Trailer: cheaper for the kitchen unit, can tow with multiple vehicles, but tow vehicle requires CDL in some states + parking footprint is larger.

Operator default: truck for most operations; trailer for festival circuit + multi-truck operators who maintain a dedicated tow fleet.

Decision Question 3 — Power source: propane or generator + electric?

Food trucks run one of two power architectures:

Propane-dominant (operator default): cookline runs on LP propane from on-board tanks (typically 2–4 × 100 lb cylinders mounted in code-compliant ventilated cabinet). Refrigeration, lighting, POS, and exhaust fans run on a small (3–7 kW) generator or shore power.

Generator-dominant: cookline includes electric appliances (induction ranges, electric fryers, electric griddles) running off a larger 10–20 kW generator. Heavier, fuel-thirstier, but eliminates propane fire-load and simplifies many state inspections.

Decision rule:

For most concepts: propane-dominant. Lower fuel cost, lighter weight, simpler refueling.

For ventless / urban / event-restricted markets: generator + electric. Some cities (Boulder, Portland, San Francisco) restrict on-board propane in certain districts.

Decision Question 4 — Hood and suppression: which configuration?

NFPA 96 applies to mobile kitchens — Type I hood is required wherever grease-laden vapor is produced. The configuration options:

Standard Type I canopy in a 16-ft+ truck: 4–8 ft length, mounted to the truck ceiling with full suppression. Operator default. Cost $8,000–$22,000 installed.

Recirculating ventless hood (UL 710B-listed): captures and treats grease vapor internally. Allows operation in jurisdictions / sites that restrict external exhaust. Limited cookline BTU capacity.

Outside / external exhaust trailer: Type I hood with exhaust through truck roof or sidewall. Required configuration in most truck builds.

State and city food-truck regulations vary widely. Verify before spec.

The standard 20-foot food truck equipment list

For a typical 20-ft truck doing tacos / burgers / sandwiches concept, $80k–$130k all-in equipment + buildout:

Cookline:

Truck chassis (used 2018–2022 step-van class): $30,000–$60,000

Body modifications + insulation + flooring: $15,000–$30,000

Misc: smallwares ($2,500), POS ($600), graphics / wrap ($3,500–$8,000), permits ($500–$3,000)

Total all-in: $90,000–$170,000

Operating profile: targets $25,000–$60,000 monthly revenue at events / route. Break-even at $18,000/mo. Profitable at $30,000+/mo with 12–22% margin.

Mobile fryer requirements

Mobile fryers face additional code requirements beyond static commercial fryer specs:

Equipment must be UL-listed for mobile operation — securing brackets, anti-tip, vibration-tolerant.

Hood and suppression must be sized for the fryer (typically 200,000+ BTU/hr requires substantial CFM).

Oil disposal must comply with local FOG (fats, oils, grease) regulations — most cities prohibit on-truck disposal; the operator must transport spent oil to a licensed receiving facility.

Fire suppression nozzle above each fryer is mandatory; a typical 2-vat fryer requires 2 nozzles.

State variances: California, Oregon, Washington, and several northeastern states require additional certifications for mobile fryer operation.

Generator sizing

Total electrical load drives generator sizing. Typical loads:

Equipment category Watts (running) Watts (startup surge)
Reach-in refrigerator (1-door) 280 1,200
Sandwich prep table 350 1,400
Reach-in freezer 350 1,500
LED lighting (whole truck) 80 —
POS + tablet + printer 60 —
Exhaust fan (small) 350 800
MUA fan (if equipped) 800 1,800
Phone / tablet / charging stations 80 —

Total continuous: ~2,500 W typical 20-ft truck.
Total surge: ~7,000 W (when several motors start simultaneously).

A 5 kW generator (running) handles continuous load with 2 kW headroom — adequate for a 20-ft truck without electric cookline.

A 7 kW generator is operator default — handles continuous + surges + future-add headroom.

For trucks with electric cooking equipment (induction range, electric fryer, electric griddle, electric combi): 12–20 kW generator.

Cluster deep-dive:

Water and waste

Fresh water tank: 40–80 gallons. Sized for service shift; fresh water is delivered or filled at depot start of day.

Gray water tank: typically 1.25× the fresh-water capacity per most state codes (so the gray tank cannot fill before the fresh empties). Sized 50–100 gallons.

Hot water: most trucks run a propane-fired tankless or 6-gallon point-of-use water heater. NSF-rated dishwasher water at 180°F is rare on trucks; most rely on 3-comp sink with chemical sanitizer instead of heat sanitizer.

Drain: gray water tank discharge requires depot or municipal-receiving connection — never on-site.

Health and permitting

Food truck health permits vary widely by city. Common requirements:

Commissary / depot agreement: most cities require trucks to operate from a licensed commissary (commercial kitchen) where deep prep, cleaning, water-tank fills, and gray-water discharge happen. Roughly $400–$1,500/mo.

Mobile food vendor permit: per city, $100–$2,500/year.

Fire marshal inspection: annual fire-safety inspection of hood, suppression, propane system.

Health inspection: routine inspection (typically quarterly) at commissary and on-truck.

Sales tax registration: state.

Insurance: general liability + auto + product liability + worker’s comp; bundled food-truck policies $3,000–$8,000/year.

TCO and operating reality

Capital recovery: most food trucks pay back capital in 14–30 months at successful operation. The right concept-market fit is the dominant variable.

Fuel + propane: $400–$1,200/month depending on hours.

Commissary fees: $400–$1,500/month.

Maintenance: trucks require disproportionate vehicle maintenance — body wear, generator service, propane regulator replacement, water pump failures. Budget $500–$1,500/month average.

Marketing / events: festival fees ($150–$2,000/event), event-organizer commissions, social media management.

Labor: 2–3 cooks during service + 1–2 prep at commissary. Total labor 25–35% of revenue.

Frequently asked questions

1. Can I build my own food truck?

The chassis and basic carpentry, possibly. The hood + suppression, propane system, and electrical must be installed by licensed contractors. The complete build typically goes through a specialty food-truck builder for code compliance and warranty.

2. Used food truck — buy or build new?

Used can save 30–50% if you find one in good chassis + hood + propane condition. The catch: hood and suppression often need recertification ($1,500–$3,000), generators need rebuild ($800–$2,500), and chassis miles matter. Verify state of certifications before purchase.

3. What’s the most-failed food-truck inspection item?

Propane system — regulator condition, hose condition, cylinder mount, leak detection. Annual inspection is mandatory; failures here are the leading cause of truck shutdown by AHJ.

4. Do I really need a commissary?

In most U.S. cities: yes. The truck cannot serve as both a kitchen and a commissary — health code requires off-truck deep prep, dishwashing, water-tank service, and gray-water discharge. A few rural states allow exemptions.

5. Concept stability — should I pick one menu and stick with it?

For the first 12–18 months: yes. Food trucks succeed by being known for one thing in their market. After establishing brand, menu evolution is fine.

6. How many events / hours can I realistically work?

Successful food trucks typically operate 5–7 days/week with 2–4 service shifts per week. Around 35–55 hours of service time + 15–25 hours of prep + transit + admin. Burn-out is real; plan staffing for 2 cooks + 1 owner-operator minimum.

7. Trailer or truck for first build?

Truck if budget allows ($90k+ build) — simpler logistics, full mobility. Trailer for tighter budget ($50k–$80k build) — saves on chassis cost, accepts the extra logistics.
