PRE-SALE! This Midsize Surface Mount Diesel Heater Enclosure fits both Alu-Cab ModCAP and Canopy Camper. Webasto heater SOLD SEPARATELY!
PLEASE NOTE! Agreeing to purchase the diesel heater enclosure has a NON-REFUNDABLE $500 return fee. This first batch of heaters will determine future production. We must be able to cover the custom fuel tank and partial components of the kit. Once we start with production on the tanks we are unable to stop or return the custom tanks.
With this first round of orders, we must reach a threshold of 10 units before production can begin. If for some reason there is an issue with production and the threshold is not met and the heater enclosure is not deliverable, the $500 NON-REFUNDABLE deposit will be returned to the customer.
Once production begins, production will take 8-10 weeks. The first production run will be for the Midsize Alu-Cab ModCAP and Canopy Camper rear passenger side mounting location.
This is the Surface Mount Diesel Heater Enclosure and related installation parts. The Webasto Air Top 2000 STC Diesel Heater is SOLD SEPARATELY.
Our Surface Mounted Diesel Heater Enclosure is uniquely designed around the Webasto Air Top 2000 STC Diesel Heater, taking advantage of the Webasto's 90° vertical mounting capability. The diesel heater enclosure is not designed to fit a specific camper or trailer brand. There are specific interior mounting brackets and cover plates to fit both mid-size and full-size Alu-Cab Canopy Campers and MODCap Campers in both the rear passenger and driver side corners. And, there is also a Universal Kit for use with any style camper, trailer or DIY build that has the appropriate size flat surface to mount on.
The Diesel Heater Enclosure is split to a 50/50 setup, keeping the fuel tank, fuel pump, exhaust and intake on the outside of the camper. The heater and controls are mounted within the inside enclosure. Since the heater is located inside the camper, the air is recirculated and monitored via the SmarTemp bluetooth controls. No extra air hoses are needed. The outside enclosure houses a custom aluminum fuel tank with electronic fuel sensor integrated within the tank. Fuel capacity is approximately 1.15 gallons.
The unique design of our Surface Mounted Diesel Heater Enclosure keeps all fuel lines and electrical lines hidden so that there is no danger of snagging anything while enjoying off-road trail rides.
Ease of Use and Simplicity were key when designing our Surface Mounted Diesel Heater Enclosure. Once installed, you only need to remove the included exhaust and intake plugs and push start. That's it! There is nothing more to do.
This is the Surface Mount Diesel Heater Enclosure and related installation parts. The Webasto Air Top 2000 STC Diesel Heater is SOLD SEPARATELY.
We suggest using an extra length of exhaust pipe if you have any type of awning or overhang that might trap exhaust fumes. We also HIGHLY suggest the use of a high quality carbon monoxide detector inside the enclosed space.

Let customers speak for us
The product is good quality
Thank you from Montreal, Quebec
In my opinion ARB is simply the best onboard compressor made including adapters and air lines
I already have one on the left side. This is for the right. Haven't installed it yet but I'm positive it will fit just fine.
Excellent fit and finish. Amazing customer service. What other company can you call and speak for 20 minutes to the owner about their products? This business is top class. I will certainly continue to spend my hard earned money with 813!
Super helpful support from Jeremy, and a great product that I'm pleased with. Thank you!
My accessory plate arrived quickly. It's top-quality; well manufactured and finished. It was well packaged to arrive in perfect condition. Now to drill some holes in it to mount my Garmin Power Switch!
Fit my 2024 Gladiator perfectly. Install took 15 minutes. Support prior to purchase was prompt and friendly. I do wish the mounting bolts were black like the panel (instead of nickel) but I’m not going to ding it a star - I’ll just chalk that up to my own OCD.
Great under seat mount. Am using it for the new brushless compressor and all works well. Great bang for the buck.
Fit and finish was great, came with high quality hardware, and paired great with a compressor mount for a full in cab air solution. 10/10
813 Fabrications truly never disappoints! Every product I’ve received from them has been top-quality, built with precision, and clearly made to last. But what really sets them apart is the incredible support and service behind the scenes. The team is responsive, knowledgeable, and genuinely passionate about what they do—something that’s becoming rare these days. It’s clear they take pride in their work, and it shows in every detail. Thank you, 813, for consistently going above and beyond.
This kit was easy to install and the quality is top notch! I will definitely keep 813 fabrication in mind for other upgrades.
I couldn’t be happier with the RotopaX mount I picked up from 813 Fabrications for my Alu-Cab Canopy Camper. The craftsmanship is top-tier — solid welds, perfect fit, and it looks like it was made by Alu-Cab themselves. It mounted up flawlessly and holds the RotopaX tanks snug and secure, even through rough off-road terrain.
What really sets 813 Fabrications apart is the attention to detail. You can tell these guys know overlanding gear and understand what real users need. The powder coat finish is rugged and clean, and everything about it feels purpose-built, not an afterthought.
Shipping was fast, and customer service was responsive and helpful. I had a couple of questions before ordering, and they got back to me quickly with answers and advice.
If you’re running an Alu-Cab Canopy Camper and want to add RotopaX fuel or water storage, this is the mount to get. 813 Fabrications has earned a permanent spot on my go-to gear list. Highly recommended.
I was looking for a bracket to use under the driver seat so my ARB compressor could breathe cool air. The plan is to mount this bracket on my under seat storage safe and run the two intake lines back over to the compressor under the passenger seat.
All the shipment was a little bit longer than I had hoped. They did contact me and said they were getting my order together and there was a little issue with packing. But it got here earlier than they had said for the later date. Also, the locks weren't working correctly so within 4 days I had a brand new set of locks that actually didn't fall apart. Communication was awesome and this is a very good product.
