Buy a Stock Food Truck or Build Custom? How to Decide

Once you have decided to buy new rather than used, there is a second decision most first time owners do not realize they are making: take a truck someone already built, or have one built around your menu. Both are legitimate. They suit different people, and the difference shows up in your workflow every single service, not on the invoice.

This is a comparison of buying a stock or turnkey new truck against commissioning a custom build. If you are still weighing a used truck, start with our guide on used trucks versus new builds instead.

The Short Version

A stock truck is faster to get and simpler to buy. A custom build costs a similar amount for equivalent quality, takes longer, and is designed around how you actually cook. The right question is not which is better. It is whether your menu is standard enough that somebody else’s layout will work for you.

Your Menu Decides the Truck, Not the Other Way Around

The most expensive mistake in this business is picking the truck before finalizing the menu. A builder with over 350 trucks behind them puts it at the top of their list of launch killers, and we would agree from our own shop.

The menu determines the cooking line, which determines the hood, which determines the suppression system, which determines a good part of your permit cost. It determines refrigeration count, which determines electrical load, which determines generator size. It determines where you stand, where the runner passes, and whether two people can work without colliding during a rush.

Consider three concepts at the same price point. A taco truck needs a flat top, a steam table and several refrigerated topping rails, all within reach of one person. A coffee truck needs clean stable power, a water system built for constant rinsing, and almost no hood at all. A barbecue truck needs a smoker, serious ventilation and holding capacity, and it needs weight distributed so the truck still drives properly. Put any of those three menus into another’s layout and you will feel it every day you trade.

The Three Things Stock Trucks Usually Get Wrong for You

Electrical load

Refrigeration, freezers, fryers, point of sale, lighting, water pumps and air conditioning all pull at once, and on the hottest day of the year they pull hardest. A stock truck’s generator is sized for the equipment list it shipped with. Add one more fridge or swap to an electric griddle and you can find yourself tripping breakers mid service.

Fixing it later is not cheap. A new commercial mobile generator in the 7 kW class lists around $7,800 before installation, and installation means panel work and a transfer switch on top. Sizing it correctly at build time costs a fraction of that.

Weight distribution

Where the heavy equipment sits affects suspension load, tire wear, braking and handling. On a custom build this is calculated as part of the design. On a stock truck it was calculated for the original equipment plan, and if you add a smoker or a second fridge later, nobody recalculates anything.

Local code

Requirements vary more than people expect. Water and waste tank sizing, handwash setup, propane routing and hood coverage all differ by jurisdiction. Oregon, for example, requires at least 5 gallons dedicated to handwashing, at least 30 gallons or twice the three compartment sink volume for warewashing, and a waste tank 15 percent larger than the fresh tank, all integral to the unit. A truck built to a different state’s reading of the code can pass there and still need work where you operate.

A custom build starts by asking where you will be operating and builds to that. It is the cheapest way to buy compliance, because retrofitting a finished kitchen always costs more than specifying it correctly once.

Warranty, and What It Actually Covers

New trucks generally come with builder coverage on workmanship and labor, typically a year, while each piece of equipment carries its own manufacturer warranty, commonly one to five years depending on the make. Two practical notes. You usually have to register the equipment with its manufacturer yourself to be eligible, and coverage on a truck someone else ordered may already be partly used up before you take delivery.

Ask any builder, including us, for the warranty terms in writing before you commit, and ask specifically who handles a failure in month eight: the builder, or you calling the equipment manufacturer.

When Buying Stock Makes More Sense

We build custom, and we still think stock is the better answer for some buyers:

• You need to be trading in weeks, not months. A contract, a season, or a location that will not wait. A build schedule cannot bend past a point, and a truck sitting on a lot can.
• Your menu is genuinely standard. Burgers, fries, basic tacos. If a general purpose cook line does what you need, you are not paying for a compromise.
• You are testing a concept and want to keep your options open before committing to a layout.
• The stock truck happens to fit. This does happen. If you walk through one and every station lands where you would have put it, buy it.

If you go this route, the discipline is the same as buying used. Confirm the suppression system is UL 300 and currently tagged, confirm the propane routing is hard piped from the regulator, confirm tank sizes against your local health department’s requirement, and get the warranty in writing.

When a Custom Build Pays for Itself

• Your concept has a specific piece of equipment at the center of it. A smoker, a pizza oven, an espresso setup, a soft serve machine. Those drive the whole design, and retrofitting one into a general purpose truck rarely goes well.
• You expect volume. Layout inefficiency compounds. Ten extra seconds per order is a real number when you are doing three hundred covers at a festival.
• You plan to keep the truck for years. The efficiency and the compliance both pay back over time.
• You operate somewhere with strict or unusual requirements. Building to the local code from the start is far cheaper than discovering it at inspection.
• You want the service life to start now. Fryers run about 7 to 10 years, ranges 10 to 15, refrigeration 10 to 20. On a new build those clocks all start when you take the keys.

Three Menus, Three Very Different Trucks

The clearest way to see why the menu drives the build is to look at three finished trucks at similar sizes. Watch where the equipment sits and how much of each build is given over to one central piece.

Put the coffee menu in the BBQ trailer and most of that space is wasted. Put the BBQ menu in the coffee van and it will not pass inspection, because the hood and suppression are not there. This is the whole argument for building around your menu rather than adapting to someone else’s. More walkthroughs are on our build videos page.

How to Decide in an Afternoon

Write your opening menu, then list every piece of equipment each item needs. Add up the electrical draw. Sketch where each station goes and walk through a busy hour in your head, including where the second person stands. Then look at any stock truck you are considering and see how many of your stations land in the wrong place.

If the answer is none or one, buy the stock truck and get trading. If it is three or more, you will be fighting that layout for years, and a custom build is the cheaper decision even though it is the larger invoice.
