Bigfoot 17 Furnace replacement

I need to put a new Furnace in my 1990 Bigfoot. But they no longer make the Atwood 7812 Furnace . Does anybody know what a good replacement model would be for my 89 Bigfoot

Thanks
Tom

I've also looked for a direct replacement and could not find one that did not require relocation of the exhaust.
I was able to rebuild mine, turns out most parts are available, I replaced the motor and regasketed the heat exchanger. As long as the heat exchanger is still in good shape it was worth doing.
Now I'm good for years to come!

The heater in my 17' Bigfoot currently works fine. Nonetheless, I am considering replacing it with a catalytic heater with no blower.

When did they stop making the Everest II? The 8012 model was a direct replacement for the model you should have (whether your trailer's an 89 or 90). I was looking just last year and they still sold them...But I sure can't find one now.

I wanted to replace mine, but didn't want to spend almost $800, and I had the same dilemma as Tom. A cheaper Suburban furnace would require cabinet modifications, cutting a new hole in the fiberglass shell and sealing the old one. This is the direct replacement, and I'm not sure why they stopped making it, if that's true.

In the end I did a minor refurbish of my furnace, which I linked in your other thread. For now, it's running great. Not sure what I'll do if I hold onto the trailer long enough to need a new one.

This place claims to still have them in stock. Might be worth checking if it's not outside your budget.
