The questions
Open any question to see why it works.
- 1
What made you start with a truck instead of a restaurant?
Answers divide into people who wanted a lower startup cost and people who wanted the mobility, and the two end up running different businesses. Anyone who says the truck was cheaper and stops there usually has a story coming about how much less cheap it turned out to be.
- 2
What did it cost to get on the road the first time, all in?
Push for the all in figure: truck, build out, permits, the first insurance payment, initial inventory, and the deposit on a commissary. The vehicle itself is often less than half of it, which is the single thing most people get wrong when planning this.
- 3
Did you buy new, buy used, or build it out yourself, and would you do that again?
A used truck with a working kitchen can be a bargain or somebody else's failed business with bad wiring. The regret in the answer tells you which risk they took and how it went, which is more useful than a general recommendation.
- 4
What broke first?
Every owner has this answer ready, and it is usually the generator, the transmission, or refrigeration that could not cope with a hot day. It doubles as an inspection list if you ever go to look at a truck yourself.
- 5
Where do you park, and how did you get that spot?
Location is most of the business and good spots are rarely advertised. Listen for whether it came through a private property owner, a city permit lottery, a brewery arrangement, or knowing somebody, because that is how a newcomer would have to get one too.
- 6
How much of your revenue is street service versus events and catering?
Plenty of trucks that look like street businesses make most of their money from private catering, booked months ahead at different margins. It changes what the business actually is, and whether it can survive three rainy weekends in a row.
- 7
What does your commissary cost, and what does it require you to do?
Most jurisdictions require a licensed commercial kitchen for prep, storage and waste disposal, and the truck cannot legally operate without one on file. It is a fixed monthly cost left out of most plans, and availability can decide where you are able to trade at all.
- 8
Which permit took the longest, and which one nearly stopped you?
Health, fire and parking come from separate offices that do not coordinate with each other, and the fire inspection of the suppression system is the one that catches people. Ask how long the whole sequence ran from first application to first day of service.
- 9
What do inspectors look at on a truck that they would not in a restaurant?
Fresh and waste water tank capacity, hot water temperature, and the propane setup are truck specific and are the usual reasons for a failed inspection. An owner who can list them without thinking has been through it more than once.
- 10
What is your best day of the week, and your worst?
The pattern is local and counterintuitive: office districts die at the weekend, brewery lots do the opposite. It also reveals how many trading days actually pay for themselves, which is usually fewer than outsiders assume.
- 11
How did you decide how big the menu is?
Truck kitchens are limited by space, power, and how many tickets one person can fire at once, so menus shrink over time rather than grow. Ask what came off and why, because that is where the operating lesson sits.
- 12
What is your food cost, and how do you know when it slips?
A specific percentage plus a method for tracking it means somebody is running a business. Vagueness here, or a number recalled from memory with no idea how it is calculated, is the most reliable sign that the truck is running them.
- 13
How many people are on the truck on a busy night, and what does each one do?
There is physical room for two or three, so labor is capped by square footage rather than by demand. This explains why revenue on a truck has a ceiling no matter how long the line gets.
- 14
What powers the truck, and how loud is the generator?
Power decides where you can park, since some venues and neighborhoods ban generators outright and some events require quiet ones or supply shore power. It is also a recurring fuel and maintenance cost that plans routinely leave out.
- 15
How much do weather and season actually move the numbers?
Rain in a walk up business does not reduce sales, it deletes them. Ask what they do in the slow months, because the answer, whether that is catering, a second job, or closing for six weeks, is much of whether this works as a living.
- 16
What does it cost to get into a festival, and does it pay?
Event fees are sometimes flat, sometimes a percentage of sales, and sometimes both, with the percentage arriving as a surprise. Owners can usually name which events pay and which ones are advertising, and that list is invisible from outside.
- 17
How do you handle a line that is longer than your ticket times?
This is what separates a busy truck from a profitable one. Answers involve prepped components, a cut down menu at peak, a separate cash line, or pre orders, and they represent years of trial and error you get for the price of asking.
- 18
What did you underspend on, and what was a waste of money?
The shape of the answer is remarkably consistent: more should have gone into the truck itself or the refrigeration, and less into the wrap, the branding, or a piece of equipment used twice and then stored.
- 19
What would make you shut it down?
It gets you an honest read on the health of the business without asking what they earn. Losing a parking spot, a transmission, or a commissary are the three that come up, and each is a risk worth planning around before you buy anything.
- 20
If I wanted to test this before buying a truck, what would you tell me to do?
The usual advice is to work a season on someone else's truck, or run a stall or pop up first. Whether they answer generously also tells you whether this is a person who will take your call again in six months.
Working out whether a food truck is a business you want
Practical guidance for the conversation itself.
Before you buy a truck
Before you buy a truck
- Work a full service on somebody else's truck, ideally a busy one. It is the cheapest research available and most owners will let you.
- Find out your local commissary requirement before costing anything else. It sets a monthly floor and in some cities it limits where you can prep and park.
- Ask the health department for the plan review requirements in writing. Building a kitchen and then finding it will not pass is the expensive version of this mistake.
- Price permits and insurance before the vehicle. Together they are often a bigger surprise than the truck.
- Sit at a spot you like for a whole lunch service and count customers and ticket times yourself.
Numbers worth asking for
Numbers worth asking for
- Average ticket and number of covers on a good service, not on a record day.
- Food cost as a percentage, and the method used to track it.
- Fixed monthly costs: commissary, insurance, permits, storage, loan payment on the truck.
- Split of revenue between street service, private catering and events.
- Trading days in a typical month, and what happens in the slowest one of the year.
If you are interviewing rather than planning
If you are interviewing rather than planning
Owners get asked the same three questions constantly: how did you start, where do the recipes come from, what is your favorite thing on the menu. You will get a far better conversation by asking about the parts nobody asks about, which are parking arrangements, generators, waste water, the fire suppression inspection, and what happens the week the transmission goes. Ask during a slow period or after service rather than during a line, and be specific about how long you want. Fifteen minutes requested honestly gets a longer answer than an open ended request for a chat.
