I just got my hands on a Fleet of unknown vintage (somewhere between 2006 and 2009, maybe) and I am refitting it. I figured I'd just pull the old furnace and pop a new Dometic model into the hole. The old furnace is a Dometic/Atwood 8516-IV. The guy I bought it from said it worked but I couldn't get it to light. Fan was okay, though.
The new furnaces are 3 inches longer than the old one. And, yes, I have learned an important lesson about removing something prior to researching a replacement!
My options seem to be:
1. Fix the old one (if possible) and put it back in. I saved the circuit board and thermostat but who knows if they work.
2. Cut 3 inches out of the wooden platform directly behind the furnace and get a new Dometic.
3. Try something entirely different like Propex or Truma (gasp$$).
I really want to go with option 2. Is there a problem if I cut down that little bump out where I drew the line in the photo? I would replace the wood on the end and patch the hole in the floor, of course.
Any advice for a newbie?
