A fried chicken truck is not a burger truck with a fryer bolted in. Chicken is a slow protein with a long cook, it has to be held hot without going soft, and the raw side of the operation needs its own space so flour and buttermilk never end up near cooked product. Every one of those facts changes the floor plan. This is the 16ft fried chicken truck we just finished for Sapphire Chicken, headed to Corvallis, Montana, to work the Bitterroot Valley and the Missoula market on US 93.
Sapphire Chicken runs crispy chicken tenders and comfort food out of the truck, with a breakfast service from 7 to 10 and a lunch service from 11 to 2. That split matters more than it sounds. Breakfast leans on the griddle and the stove, lunch leans on the fryers, and the truck has to turn over between the two without a crew of six. Here is how we built it, and what it takes to run a mobile unit across the Bitterroot and Missoula County line.

Two fryers, a breading station, and a proofer
The three pieces that make this a chicken truck are the pair of 40 pound fryers, the dedicated breading station, and the 9 pan proofer and hot box. They solve the three problems that sink most chicken operations.
Two fryers instead of one is about recovery, not capacity. Drop a full basket of tenders into a single fryer and the oil temperature falls forty or fifty degrees, and everything after that basket cooks slower and greasier until the burner catches back up. With two 40 pound wells you can stagger drops, hold one at chicken temperature and run the other for fries, and keep the line moving through a lunch rush instead of stacking tickets behind a recovering pot.
The breading station gives the raw side its own real estate. Flour, buttermilk, and seasoned dredge live in one place, away from cooked product and away from the service window, which is both a food safety requirement and a speed requirement. A crew that has to clear a prep table to bread a batch loses the rush.
The 9 pan proofer and hot box is what lets a small crew serve fast food. Chicken gets par cooked ahead, held at temperature in the box, and finished to order. That is the standard fried chicken service model, and it is the only way to hand a customer a tender in ninety seconds instead of twelve minutes. Nine pans is enough staging for a breakfast push and a lunch push in the same day.
The rest of the cook line
Alongside the fryers, the truck carries a 36 inch griddle and a two burner stove, both under the hood. The griddle is the breakfast engine, running eggs, sandwich buns, and hash in the morning window, and it doubles as a bun toaster and a smash surface at lunch. The two burner stove covers gravy, sauces, and anything that needs a pot. The whole cooking wall is stainless steel, as is everything else in the box, and the floor is aluminum diamond plate, which is the finish that actually survives a fryer line and hoses out clean at the end of a shift.
Cold side and dry storage
Chicken volume is a cold storage problem before it is a cooking problem. This truck carries four separate refrigeration units, which is more than most 16ft builds and exactly right for this menu.
A standup reach in refrigerator holds the day’s raw and marinating product. A 27 inch refrigerated sandwich prep table holds the build line for sandwiches and keeps toppings at temperature under the lid, so nobody is opening a big door forty times an hour. A standup full size freezer carries fries, backup product, and the frozen inventory that keeps a truck from running out on a Saturday. And a merchandiser refrigerator holds cold drinks where the customer can see them, which is the highest margin item on any truck and the easiest upsell at the window.
Power, and why this truck runs a 12kW generator
The cooking is propane. The generator carries everything else, and on this build everything else adds up fast. Four refrigeration compressors, an 8 gallon water heater, the air conditioner with heat, the hood fan, and LED lighting inside and outside the truck all pull from the same 12kW unit. A smaller generator would run this load right up until three compressors kicked on at once on a hot afternoon with the air conditioner going, and then it would not.
The generator sits in its own vented compartment on the street side with a mesh door, mounted so it can be serviced without pulling anything apart and vented so it is not heating the box it is powering. If you want the longer version of how we size these, we wrote it up in our food truck generator size guide, and there is a load by load breakdown in food truck electricity and water consumption.

Water, sinks, and the plumbing
The truck runs a 30 gallon fresh water tank and a 40 gallon grey water tank, both mounted underneath and both reachable for a fast fill and dump. Grey capacity has to exceed fresh, and 40 against 30 gives about a third more room, which is the margin health inspectors look for and the margin you want on a long event day. An 8 gallon water heater feeds the hand wash sink and the three compartment sink, and the whole setup is what a Montana plan reviewer expects to see on a fully enclosed mobile: permanently mounted tanks with hookups you can service in a parking lot.
Montana winters are the other half of the plumbing question. A truck based in Corvallis will see subzero mornings, and water lines that were not routed and insulated for it will split the first cold snap. We run freeze protected plumbing and insulated walls on every northern build, and the reasoning is in our guide to winterizing a food truck for cold weather.
Fire suppression on a two fryer line
Two fryers and a griddle under one hood is a serious fire load, and it is the part of the build that fire marshals look at first. This truck carries a fire suppression system over the cook line, a Class K extinguisher for the fryer oil, and A/B/C extinguishers for everything else. Class K is not optional on a fryer truck. Cooking oil fires do not respond to a standard dry chemical extinguisher, and an inspector who finds only an ABC on a fryer line will fail the unit. We break down how these systems are specified and tagged in our food truck fire suppression system guide.
The service window
The truck opens through a 5ft service window with an awning door that gives the customer cover in Montana weather, plus a bug screen and self closing doors on the entry. LED lighting runs through the interior and along the outside of the truck, which does more work than people expect at a night event where the truck is the only lit thing in a gravel lot.

Licensing a food truck in Ravalli County and Missoula County
Montana works differently from Colorado, and a truck based in the Bitterroot that also wants to work Missoula has to understand the county line.
The Montana Department of Public Health and Human Services sets the retail food establishment rules statewide, but the county is where the work happens. For a truck based in Corvallis, that is Ravalli County Environmental Health in Hamilton, which handles the plan review, the inspection, and the approval. Plan review should be submitted before the build is finished, and the county asks for 30 to 60 days. Every mobile unit in Ravalli County also needs a backup commissary kitchen agreement on file, and that is not waived for a self contained truck.
Here is the part operators miss. A Montana mobile license does not simply travel. Ravalli County is direct about it: a mobile can work county to county across Montana, but it needs approval from each county jurisdiction it works in, and they ask you to contact the other county at least a week ahead. So a Bitterroot truck taking a booking in Missoula needs to clear it with Missoula Public Health, not just show up. Missoula runs its own plan review through the Missoula City-County Health Department on West Alder Street, and for fully enclosed mobiles it expects permanently mounted water and waste tanks with RV compatible hookups, a plumbed hand sink with hot and cold water, and the three compartment sink and hood package that the menu calls for. A fried chicken menu calls for all of it. We keep a running breakdown of both sides of that process in our Montana food truck permits guide and our Missoula inspection requirements guide.
One thing that goes in the operator’s favor: Montana has no general statewide sales tax, and neither Missoula nor the Bitterroot is one of the small number of designated resort communities that levy a local resort tax. Annual state license fees are set in statute and are modest by national standards. Compared to running the same truck in Colorado, where you are collecting state, county, city, and special district tax at every stop, the Montana paperwork after opening day is light.
The Bitterroot and Missoula market
The Bitterroot Valley runs about fifty miles south from Missoula along US 93, between the Bitterroot Mountains on the west and the Sapphire Mountains on the east, which is where this truck gets its name. Ravalli County has grown to roughly 49,000 people, up almost 22 percent since 2010, making it one of the fastest growing counties in Montana and now the seventh largest. Hamilton is the county seat and carries the NIH Rocky Mountain Laboratories campus along with the county’s medical and retail base. Stevensville, Corvallis, Victor, Florence, and Darby fill in a corridor of small towns where a good truck can build a route rather than fight for one spot.
Fifty miles north, Missoula is the anchor. The University of Montana brings roughly ten thousand students, and Washington-Grizzly Stadium seats 25,217 with a record crowd of 27,340 set in November of 2025 against Montana State. Griz Saturdays put more people downtown than anything else in western Montana. Caras Park hosts Out to Lunch every Wednesday from 11 to 2 through June, July, and August, which has run since 1986 and is Montana’s longest running outdoor food and music festival, with around fifteen food vendors a week. Add the farmers markets, the brewery scene, the summer festival calendar, and the Ravalli County Fair in Hamilton in August, and there is enough on the calendar to keep a truck working from spring through fall on both ends of the highway. There is more on the local scene on our Missoula food truck builder page.

Altitude in western Montana
Missoula sits at about 3,209 feet and Corvallis and Hamilton around 3,570. That is real altitude, but it is a much softer hit than the Front Range. Atmospheric gas appliances lose roughly four percent of rated input for every thousand feet above two thousand, which puts western Montana around five to six percent. For comparison, Denver runs about thirteen percent and Jackson Hole about seventeen.
Five percent still matters on a fryer line, because a fryer that recovers slowly compounds across a rush. We size the burners and the gas supply for the derating so the fryers hold temperature between drops. It is a smaller correction than the ones we make on our Colorado builds, and we make it anyway.

Frequently asked questions
Why does a fried chicken truck need two fryers?
For oil recovery. A single fryer drops forty to fifty degrees when a full basket goes in, and every order after that cooks slower and absorbs more oil. Two 40 pound wells let you stagger drops and dedicate one to chicken and one to sides, which keeps the line moving through a rush.
What does the proofer and hot box do on a chicken truck?
It holds par cooked chicken at safe temperature so orders can be finished to order in a minute or two instead of a full cook cycle. Nine pans of staging is what lets a two person crew serve a lunch rush without a twelve minute ticket time.
Who licenses a food truck in the Bitterroot Valley?
Ravalli County Environmental Health in Hamilton handles plan review, inspection, and approval for mobile units based in Corvallis, Stevensville, Hamilton, and the rest of the valley, under the Montana DPHHS retail food establishment rules. Allow 30 to 60 days for plan review, and expect to provide a backup commissary kitchen agreement.
Can a Bitterroot food truck work events in Missoula?
Yes, but not automatically. A Montana mobile can travel county to county, and each county jurisdiction has to approve it. Ravalli County asks operators to contact the receiving county at least a week ahead, so a Missoula booking means clearing it with Missoula Public Health before the date.
Does altitude affect a food truck in Missoula?
Somewhat. Missoula is about 3,209 feet and the Bitterroot around 3,570, which costs atmospheric gas appliances roughly five to six percent of rated input. That is well under what Denver or Jackson Hole take, but we still size the fryer and griddle burners for it so the cook line holds temperature.
How long does a build like this take?
A custom build runs about six weeks. We can source the truck or build out a chassis you already own, and we deliver finished units to operators across Montana, Wyoming, Colorado, and the rest of the Mountain West.
