A BBQ trailer with a porch puts the smoker on an open deck behind the enclosed kitchen, so the fire, smoke and ash stay outside the food-prep space. At Eastcoast Concessions the porch is a Premium Box option — 6 feet for $800 or 8 feet for $1,000 — and it comes out of the trailer's overall length.
Ask a pit operator why their trailer has a porch and the answer is never decoration. A porch is an open deck at the back of the trailer — half walls, a removable back gate, and a half door with a step — and it exists so the smoker can run in open air while the enclosed kitchen behind it stays clean, cool, and free of ash.
That one decision changes three things at once: where the fire lives, how the trailer tows, and how much kitchen you end up with.
| Decision | Pit inside the enclosure | Pit on a porch |
|---|---|---|
| Ventilation | Solid-fuel hood and duct kept separate from all other exhaust, with a spark arrestor | Open-air cooking; overhead ventilation depends on whether the porch is roofed and on your inspector |
| Kitchen conditions | Radiant heat, smoke and ash in the prep space | Fire, ash and smoke stay outside the food-prep area |
| Towing | Pit can sit over or ahead of the axles | Pit sits behind the axles, so tongue weight has to be managed |
| Space | Full enclosed length, minus the pit's footprint | Porch comes out of overall length: 18 feet with a 6-foot porch is a 12-foot kitchen |
Porch sizes and pricing come straight from the configurator: a 6-foot porch is $800 and an 8-foot porch is $1,000 on a Premium Box, and neither adds build time. The rest of the cost math is the same as any custom concession trailer.
A porch is the open section at the back of a concession trailer. On an Eastcoast Concessions build it is specified as half walls, a removable back gate, and a half door with a step — a working deck, not a viewing platform. The pit sits on it, the fire runs on it, and the enclosed kitchen starts where the porch ends.
There are two ways to get one. On the Premium Box it is an option under Structure & Frame: a 6-foot porch at $800 or an 8-foot porch at $1,000, and choosing one rules out the other. Neither adds a day to the build. The Ironstream takes the other route and comes with a porch designed in, built for open-air cooking rather than for a hood.
The detail that catches people is the length math. The porch is measured out of the trailer's overall length, not added to it. Order an 18-foot trailer with a 6-foot porch and what arrives is a 12-foot enclosure with a 6-foot porch on the back. If the kitchen has to be 16 feet and the pit needs 8 feet of deck, the trailer you are ordering is 24 feet, and the Premium Box runs from 12 to 26 feet to allow for exactly that.
Solid fuel makes its own rules, and they are strict. Under NFPA 96, the fire code for commercial cooking ventilation, an exhaust system serving solid-fuel equipment has to be separate from every other exhaust system — you cannot run the smoker and a griddle into the same hood and duct. The solid-fuel exhaust needs a spark arrestor to keep airborne embers out of the ductwork, installed at least 4 feet above the cooking surface so sparks lose their heat on the way. Grease-removal devices in a solid-fuel hood must be steel or stainless and approved for solid-fuel use, and the maintenance clock is faster than a normal kitchen: inspected and cleaned monthly, combustion chamber scraped to bare metal weekly. These are the NFPA 96 rules for solid-fuel cooking, not preferences, and your inspector will know them.
That is the burden a pit inside the enclosure brings with it, and it is the burden a porch is meant to avoid. Cooking in open air is a different situation from cooking under a hood in a sealed box.
What a porch does not do is settle the question for you. NFPA 96 states that it applies to cooking equipment used in fixed, mobile, or temporary concessions — trucks, buses, trailers, pavilions, tents, or any form of roofed enclosure. Whether your porch reads as open air or as a roofed enclosure is a design detail, and the authority having jurisdiction makes the call. Get your fire official's and health department's requirements in hand before you approve drawings, not after the trailer is welded. Eastcoast Concessions builds to the applicable code; the inspector still signs it off.
The ventilation argument is the one everyone makes first, but ask an operator who has worked both and they will talk about the room. A pit running for twelve hours throws radiant heat into whatever space it occupies. Put it inside a 7-foot-wide box in July, next to a person plating food, and you have a working condition problem before you have a code problem.
Ash is the other one. Solid fuel has to be cleared from the chamber at least once a day into a covered metal container of 16-gauge steel or heavier, no larger than 20 gallons. Fuel cannot be stored closer than 3 feet to a metal solid-fuel appliance, and what you keep on board is limited to roughly a one-day supply. Noncombustible flooring generally has to extend 3 feet in all directions around the appliance. Every one of those clearances is easier to satisfy on a deck built for it than inside a kitchen that also has to hold a prep table, a sink line, and two people.
This is the tradeoff nobody mentions in the showroom. A porch pit sits at the very back of the trailer, behind the axles, and that works against you.
Aim for 10 to 15 percent of the trailer's loaded weight on the tongue. When too much mass sits behind the axles, the trailer becomes less resistant to lateral disturbance: it starts to rotate slightly around the hitch, the tow vehicle answers, and the motion grows instead of damping out. A rig that feels fine at 45 can be unstable at 65. A smoker trailer that tows badly is usually a balance problem, not a driver problem.
The build answers are ordinary engineering. A competition-size offset with cabinets, water and fuel commonly puts a loaded rig in the 3,000 to 3,500 pound range, which is why a tandem-axle chassis on two 7,000-pound axles — roughly a 14,000-pound gross rating — is a typical spec. The frame gets reinforced where the pit lands, because a heavy offset concentrates its load on a short span and a chassis built for evenly distributed kitchen equipment can flex there over time. And the heavy items inside the enclosure go forward, ahead of the axles, to buy back the tongue weight the porch just spent. That is a drawing-stage decision, which is the argument for spec'ing the pit before the trailer rather than after.
An honest accounting: the porch is cheap and the space is not. Eight feet of deck is $1,000 as an option and eight feet of enclosed kitchen you no longer have. On a Premium Box the interior is 102 inches wide, so every foot of length you give up is real counter, real storage, or real room for a second person to work.
The operators who are happiest with a porch are the ones whose product is the pit — barbecue where the smoke is the whole offer, and where the enclosed side only has to hold holding cabinets, a sink line, and a service window. Operators running a broad menu with a fryer, a flat top and a full prep line usually want the length inside and the pit handled another way. The same questions you would ask when sizing any food trailer decide it: menu, service window, prep space, water and power.
At Eastcoast Concessions a purpose-built BBQ trailer typically starts around $58,000, with larger and more heavily equipped builds running from $75,000 to $135,000. The porch itself is a small line inside that. The payment schedule is staged. Premium Box builds: $495 Virtual Blueprint to start, credited toward the 25 percent deposit. All other builds: a 25 percent deposit starts your build. A further 25 percent is due about four weeks later, and the remaining balance is due on pickup. Before ordering, call 201-425-8573 or schedule a consultation. The build runs roughly 14 to 20 weeks, with the production clock starting when you approve the drawings rather than at deposit. If you are weighing how to fund it, we covered how operators actually pay for a build separately.
Two practical points that catch first-time buyers. Equipment is NSF-compliant, meaning it meets the sanitation standard, and the trailer is built to the applicable code — but you supply your local health department's requirements and you get the finished trailer inspected and approved in your jurisdiction. And there is no delivery: every trailer is built to order in Wayne, New Jersey, and you collect it in person. Buyers come from all over the country, but the trailer is picked up at the shop, so plan the tow home as part of the purchase.
It is the open deck at the back of the trailer, specified as half walls, a removable back gate, and a half door with a step. The smoker sits on the porch and runs in open air, so heat, smoke and ash stay outside the enclosed kitchen where food is prepped.
No. The porch is measured out of the overall length you order, not added to it. An 18-foot trailer with a 6-foot porch gives you a 12-foot enclosed kitchen. If you need a specific amount of kitchen, add the porch length to it and order the total.
That is the inspector's call. NFPA 96 applies to cooking equipment used in trailers and in any form of roofed enclosure, so whether an open-air pit on a porch falls inside those requirements depends on the porch design and on your local authority having jurisdiction. Get their requirements before drawings are approved.
On a Premium Box, a 6-foot porch is $800 and an 8-foot porch is $1,000. They are alternatives rather than add-ons to each other, and neither adds build time. The Ironstream comes with a porch designed in.
A purpose-built BBQ trailer from Eastcoast Concessions typically runs about $58,000, with larger builds between $75,000 and $135,000 depending on pit size, porch length, hood, and finish.
