Twelve feet. Tacos, burritos and espresso. People hear that combination and assume we have got the length wrong, because the instinct is that a wide menu needs a big trailer.
It does not. What a wide menu needs is a cook line laid out so that every station can be reached from one spot, and a trailer built well enough that the extra equipment does not shake it apart. This one was built for a customer in El Paso County, Colorado, and it runs a griddle, a two burner, a fryer and an espresso machine out of twelve feet.

How twelve feet carries three menus
Tacos and burritos are mostly flat top work: meat, onions, tortillas and quesadillas on a griddle. Rice and beans want a pot. Chips want oil. Coffee wants its own corner and its own power. Lay those four jobs out in a straight line under one hood, put the cold storage across the aisle, and one cook can work the whole menu without walking.
The hot line, all Atosa CookRite:
- An Atosa ATMG-24, a 24 inch countertop griddle with two burners at 30,000 BTU each and a three quarter inch polished steel plate. Thick plate is the point on a taco line. It holds its heat when a full order of cold meat goes down.
- An Atosa ACHP-2, a 12 inch two burner hotplate at 64,000 BTU in total, for the rice, the beans and the salsa that need a pot rather than a plate.
- An Atosa CookRite floor fryer for chips and anything else that comes out of a basket.
All three sit under a Type 1 hood with a wet chemical fire suppression system over the cook line. The suppression bottles are mounted on the wall, and there are ABC and Class K extinguishers inside the door.
Across the aisle is the cold side: a sandwich prep table for toppings, salsas and tortillas, and an Atosa reach in refrigerator.
Where the espresso machine goes
There is a work table on the line with room left for an espresso machine. That is the part of this build the owner should think hardest about, because the machine decides the electrical, not the other way round.
A full size two group commercial machine like the Nuova Simonelli Appia Life wants a 220 volt circuit and draws about 3,400 watts, plus a water line and a drain. The compact two group version of the same machine runs on 120 volts at 1,500 watts. A single group machine can be smaller still. On a 12ft trailer running off a generator, that is the difference between a machine that just works and one that needs a different generator. Choose the espresso machine first, then we wire the circuit to suit it.
Why the propane lives outside
The propane tanks sit on the tongue in expanded metal cages, and the gas lines run underneath the floor, outside the trailer, rather than through the kitchen.
That is not a style choice. The national propane code, NFPA 58, requires the containers on a mobile food unit to be on the outside of the vehicle, or in a cabinet that is sealed to the inside and vented to the outside. The reason is simple: propane is heavier than air. A leak inside a closed trailer pools on the floor where the cook is standing. A leak in an open cage on the tongue blows away. The same logic puts the gas lines outside the floor, where a loose fitting vents to the open air instead of into the kitchen.
The same code wants piping protected from damage, including in an accident, and the system pressure tested and then tested again every year. The fire code section written for mobile food vehicles caps the total propane on board at 200 pounds and wants the containers mounted so they cannot move. Expanded metal does both jobs: it holds the tanks and it lets air through.
The trailer itself
This is a seamless trailer. The aluminium skin is bonded rather than screwed or riveted to the frame, so there are no fastener holes through it. That matters more on a food trailer than on a cargo trailer. Screwed skins tend to crack around the screws over time from road vibration, and every crack is a way in for water. On a food trailer, water in the walls means insulation that stops working and a kitchen that smells of damp by the second winter.
It sits on heavy duty double axles. A tandem axle trailer is more stable at speed, carries more weight, and if a tyre lets go on the highway the second axle keeps it in line. Colorado law requires brakes on any trailer with a gross weight of 3,000 pounds or more, and a fully equipped food trailer is well past that, so budget for the brake controller on whatever is towing it.
There is a ram door at the back and a 5ft service window on the side. Inside it is stainless throughout, with an aluminium diamond plate floor and LED lighting inside and out. Every piece of equipment is bolted to the floor with washers. A trailer gets shaken harder on a gravel lot than a truck does on the highway, and equipment that is not bolted down walks.
Home run wiring
Every circuit in this trailer runs individually from the panel to the thing it powers. That is called home run wiring, and the panel legend shows it: lights, extraction fan, water system, sandwich prep, fridge and an extra outlet, each on its own breaker.
The alternative, which is cheaper and very common, is to daisy chain several things off one circuit. The problem shows up on a Saturday. A failed light or a wet outlet trips the breaker, and the refrigerator on the same circuit goes off with it, and nobody notices until the food is warm. With home run wiring, a fault takes out one thing, the breaker tells you which one, and the fridge keeps running.
Plumbing is a hand wash sink with a splash guard and a three compartment sink, with towel and soap dispensers mounted beside them.
Getting a food trailer licensed in El Paso County
El Paso County is a bigger and more fragmented area than most people expect, and where you trade inside it changes who you deal with.
The health licence
El Paso County Public Health issues the retail food licence for a mobile unit, and it requires a plan review for any new mobile unit that has not been licensed in the county before. Colorado’s 2025 fee law caps the 2026 licence at $481 a year for a full service mobile unit and $338 for prepackaged only, with a $155 plan review application fee. Those caps rise in 2027 and 2028. Counties may charge less, so confirm the current figure with the county when you apply.
The county’s mobile unit plan review packet is the document that shapes the build. Among other things it requires:
- A waste water tank at least 15 percent larger than the fresh water tank.
- A hand sink with a hands free, continuous flow of 100F water under pressure.
- At least 3 gallons of water per hand sink per hour of operation.
- Enough fresh water to refill the dish sinks at least every four hours, and a three compartment sink big enough for your largest utensil.
- A report back to your commissary every 24 hours, unless the unit has been approved as self contained.
Colorado Springs
If you trade inside the city of Colorado Springs, two more things apply. The city is a home rule city and collects its own sales tax, at a city rate of 3.07 percent and a combined rate of 8.20 percent, and the city stopped charging for new sales tax licences in 2023. If you sell from the public right of way, you also need the city’s Mobile Food Vendor License, which is $110 a year for your first unit and needs your county health approval, a planning and land use review, and your sales tax approval before it is issued.
Fire
Colorado Springs Fire Department covers the city, which is on the 2021 International Fire Code. Notably, the city’s own amendments delete the code’s mobile food vehicle section entirely, so ask the fire department directly what it inspects and charges rather than relying on the model code. Outside the city it is a patchwork: unincorporated El Paso County is served by around twenty separate fire protection districts, including Falcon, Black Forest, Cimarron Hills, Security and Tri-Lakes Monument. Find out which one covers your commissary and your regular pitches before you book an inspection.
Working elsewhere in Colorado
Since 1 January 2026, HB 25-1295 has made a fire permit from one Colorado jurisdiction valid in others, as long as it was issued by a certified fire inspector under the current fire code, and you give 14 days notice before trading somewhere new. Because Colorado Springs is still on the 2021 code, check with the destination jurisdiction before assuming a Springs permit travels with you.
Where a taco and coffee trailer earns around Colorado Springs
El Paso County is one of the largest counties in Colorado, with about 757,000 people, and Colorado Springs itself is close to 495,000. It is also a military town. Fort Carson alone has around 23,700 active duty soldiers and a workforce of nearly 90,000 counting families, and the Air Force Academy and the Space Force installations add thousands more. That is a population that starts early, eats on the move and wants a breakfast burrito and a coffee before seven.
That is the real argument for putting espresso on a taco trailer. Coffee carries the morning, tacos and burritos carry lunch and the evening, and one 12ft trailer works three dayparts instead of one.
Regular places to trade include Food Truck Tuesdays at the Pioneers Museum downtown, which ran through late August in 2026, the Colorado Farm and Art Market on Wednesday afternoons from June to early October, and the Old Colorado City market on Saturday mornings.
What a build like this costs
Custom food trailers start at $40,000 and custom food trucks at $55,000, with a typical 16ft truck around $72,000 and a 22ft around $110,000. A 12ft trailer sits toward the lower end of that range, and a trailer is usually the cheaper way to get a full cook line because there is no engine or drivetrain to buy.
The parts of this build that cost more than a basic trailer are the ones that make it last: the seamless skin, the heavy duty double axles, the hood and suppression, home run wiring, and the espresso circuit once the machine is chosen. Build time is about six weeks from order.
Frequently asked questions
Can a 12ft food trailer handle a full menu?
Yes, if the line is laid out properly. This 12ft trailer runs a 24 inch griddle, a two burner hotplate, a floor fryer and space for an espresso machine, with a sandwich prep table and a reach in refrigerator across the aisle. What a wide menu needs is a line one cook can work without walking, not more length.
Where should propane tanks go on a food trailer?
Outside. NFPA 58 requires containers on a mobile food unit to be on the outside of the vehicle or in a cabinet sealed to the inside and vented to the outside. Propane is heavier than air, so a leak inside a closed trailer pools on the floor. On this trailer the tanks sit in expanded metal cages on the tongue and the gas lines run under the floor, outside the trailer.
What is home run wiring on a food trailer?
Every circuit runs on its own from the panel to the item it powers, with its own breaker. A fault on one circuit, such as a failed light, then cannot trip the breaker that feeds the refrigerator. It costs a little more than daisy chaining circuits and saves food and service when something fails.
Can you run an espresso machine on a food trailer?
Yes, but choose the machine before the wiring. A full size two group machine such as the Nuova Simonelli Appia Life needs a 220 volt circuit and about 3,400 watts, plus water and a drain. The compact two group version runs on 120 volts at 1,500 watts. That difference decides the circuit and often the generator.
Who licenses a food trailer in El Paso County, Colorado?
El Paso County Public Health issues the retail food licence after a plan review, capped at $481 a year for a full service mobile unit in 2026. Inside Colorado Springs you also need a city sales tax licence and, for selling in the public right of way, a Mobile Food Vendor License at $110 a year. Fire inspection is by Colorado Springs Fire Department inside the city or by your local fire protection district outside it.
Does a food trailer need brakes in Colorado?
Colorado requires brakes on any trailer with a gross weight of 3,000 pounds or more, with breakaway braking. A fully equipped food trailer is well over that, which is one reason trailers like this one sit on heavy duty double axles.
