Been using it for a few months now and works great! Great price (around 400) for a new unit! You can re-use your old sheet metal enclosure, a DIY'er can swap em out.

The furnace was delayed in transit and took a week to get.The furnace came VERY well packaged. Fits perfectly into the housing . Works great.Things to keep in mind. My orginal furnace had the gas inlet at the front beside the circuit board. This furnace came with the gas inlet at the back of the furnace on the same side.So make sure you have enough gas line.Hope not to have to buy again but totally recommend.In the one picture Left is original and right is the new one. The other two pictures are of the new one.

Perfect replacement for SF35FQ Suburban RV furnace. Switched out fine using the old housing and saved a good chunk of money!

Furnace works less than 1/2 of the time. Definately does not work when its freezing out and I need it to keep the rv tanks from freezing. Looks like I need to return it. VERY disapointing! I would not buy it again.UPDATE: Tech came out and replaced the board. Furnace worked for a day and a half before failing again. I will NOT buy surburban appliances again......warrenty support is also appalling.2nd UPDATE: tech made a 2nd visit to repair furnace again. Replaced 2 boards with suburban boards. Both failed to work. Tech found bad relays on the suburban boards. After 3 weeks furnace is still not working.Suburban refuses to pay the warrenty repair bill. DO NOT BUY SUBURBAN FURNACES

I had a 30,000 btu and decided to upgrade. Honestly it makes a huge difference. It puts out a little more power and doesn’t use as much propane. The wires came already spliced for you. It’s normally loud when you turn it on but this one was a little quieter and smoother starting up. Hands down highly recommend

I replaced the core from my 30000btu suburban with this one despite the description not stating it's compatibility. It was an easy swap, spend more time cleaning the dust. Only complaint is the exhaust/intake ports exterior insert was bent pretty bad but otherwise it has been great, had no problem keeping my rv toasty in sub freezing temperatures

I kept on buying parts for my existing camper furnace. Got tired and started to look around online and stores within my area to only find it to be really expensive. This one came up on Amazon and I ordered it right away. This is a whole unit and goes in your existing case. Mine was SF-35F and I bought this and it fits perfectly. There are no issues and practically plug and play.

The core fit in the place of a 20000btu. It worked as designed. The dimensions show that it is 12” wide witch is incorrect, it is 17” wide.
