I honestly don't even know where to start. Any advice or guidance would be greatly appreciated.
I would recommend replacing it with the same size Suburban furnace. It should pretty much be a bolt in replacement.
To order a replacement you need to know what model number it is. Odds are its an NT20 or NT30 depending on the length of your motorhome.
Once you determine size then find the a source for the replacement and also get the size specs for the new one. Compare the old and new sizes. They should be close enough in size that it should just fit in place.
Keep in mind removing the old furnace won't be a simple task. It will take some work and more than likely a few choice words to extract the old one.
