What should I test on a used food truck before I buy it?

Paperwork tells you what the truck is supposed to be. A test day tells you what it is. Arrange to be there for a real cook-off or a full service shift, with the seller’s consent, and bring someone who knows kitchen equipment. Take notes and photos as you go. The goal is to see the truck under the strain it will face when you own it.

Power, cold and heat under load

Run the generator or shore power with every appliance on at once, not one at a time. Watch whether anything trips or struggles. Check that the refrigerators and freezers hold their temperature through the whole shift with a thermometer you brought yourself. Listen for compressors that run constantly. Cook the menu items you plan to sell and see how the burners and fryers keep up.

Water, hood and gas

Fill the fresh water tank, run the hot water and the sinks, then check that the grey-water tank drains and does not smell or leak. Look at the hood and fire-suppression system for current service tags. Gas lines and connections should be checked by a licensed technician, not by eye. Ask for any recent inspection records and compare them with what you see.

The vehicle itself

Walk the body and frame for rust, soft spots and old repairs. Check the tires, brakes and lights, then book a mechanic’s pre-purchase inspection of the vehicle. A kitchen can be perfect on a truck that cannot be driven safely. If the tests find problems, list them, get a repair estimate from a qualified trade, and use that in your conversation with the seller. This due diligence guide covers the document side.
