This one just rolled out to Billings, Montana. It’s a 12-foot funnel cake and ice cream trailer, built from scratch at our Woodland Park, Colorado shop and shipped up to MT. Here’s the full breakdown on what went into it and why we built it the way we did.
Funnel cakes and ice cream is one of those combos that just works. You get the hot side and the cold side, the crispy fried dough with powdered sugar and the soft serve, and between the two you’ve got something for basically everyone who walks up to the window. The whole concept fits cleanly in 12 feet, which is what makes it such a strong play for events, fairs, and festivals where a smaller footprint actually gets you better placement.
This particular trailer was built for someone getting into the Roundup FFA Alumni circuit and the county fair scene around Billings. That crowd wants fast service and simple menu items done right, which is exactly what this layout is set up to deliver. One person can run the whole trailer solo during a steady rush, and two people can work it during a peak without getting in each other’s way.
The build
- Length: 12 feet
- Concept: Funnel cakes and ice cream
- Built in: Woodland Park, Colorado
- Delivered to: Billings, Montana
- Build time: 6 to 8 weeks from approved design
The customer came to us with the menu concept and we worked through the layout together using our interactive builder. From approved design to trailer on the road, the timeline ran the standard 6 to 8 weeks. Everything was fabricated and wired in our Colorado shop.

Notes on the choices we made
Why 12 feet and not bigger
There’s a reason most funnel cake and ice cream operations don’t need a 16 or 20 foot trailer. The menu is tight, the equipment list is short, and the workflow is linear. You take the order at the window, pull the ice cream or drop the funnel cake batter, plate it, and hand it over. A longer trailer just means more floor to mop at the end of the night and a heavier rig to tow between events. Twelve feet keeps the build cost lower, the tow vehicle requirements manageable, and the setup time fast.
Stainless steel cooking wall, FRP everywhere else
The wall behind the fryer gets stainless steel because that’s where the grease splatter hits and where heat builds up. Stainless is easy to wipe down after a shift and it doesn’t absorb oil or stain the way other materials will over time. The rest of the interior is FRP, which is the industry standard for food trailer interiors. It’s smooth, non-porous, NSF approved, and cleans up fast. Montana health inspectors like it because it checks every box on their sanitation requirements without any discussion.
The fryer and the ice cream machine on the same circuit
People sometimes worry about running a deep fryer and an ice cream machine off the same generator. It’s a valid concern if the generator is undersized, but the 12 kW unit on this trailer handles both with room to spare. The fryer draws the most power during initial heat-up, and the ice cream machine pulls hardest during the compressor cycle. Those peaks rarely overlap in practice, and even when they do, 12 kW covers it comfortably. We spec generators this way on purpose so the operator never has to think about what’s running and what isn’t.
The 30/40 gallon tank setup
Funnel cake operations go through more water than you’d expect. Between the three-compartment sink for washing fryer baskets and utensils, the hand wash sink that health inspectors want to see used constantly, and general cleanup, a smaller tank setup would mean stopping to refill mid-event. The 40-gallon grey water tank gives the operator room to run a full day at a busy fair without needing to find a dump station. Both tanks sit under the trailer, so they don’t eat into any of the interior workspace.
Montana DPHHS requirements, built in from the start
Montana’s mobile food licensing goes through the Department of Public Health and Human Services, and the key document is the Mobile Food Establishment Plan Review Application. That needs to be submitted at least 30 days before the operator plans to open, and it goes to the local City-County Health Department. In Billings, that’s RiverStone Health in Yellowstone County. The trailer is built to satisfy plan review requirements out of the box: separate hand wash sink, three-compartment sink, hot water heater, and a layout that inspectors can sign off on without requesting modifications. We also provide a complete plan review packet to every Montana customer so they can submit the application and get through the process without surprises.
Billings summers are the real season
Billings sits at about 3,100 feet and gets genuinely hot in July and August, with highs regularly in the 90s. That matters for two reasons. First, the ice cream machine is working harder when the ambient temperature is up, so the 12 kW generator’s headroom is doing real work keeping everything cold. Second, funnel cake oil holds temperature differently when the air around the fryer is already warm, so heat-up times are shorter but oil management gets more important. Operators who are new to frying in hot weather should plan on checking their oil temperature more frequently during the first few events and adjusting their thermostat accordingly. Not a build issue, just an operating note for the Yellowstone Valley summer circuit.
