Has Anyone Replaced their 42K BTU Furnace???

[stanleyz]

If you have replaced your furnace please tell me how it went. Did you replace just the control card? How did that go? Did you replace with the new Q model, if so is that quite enough to be worth the 800 bucks? Any and all info would be appreciated.

My furnace works OK. It warms the RV quite well. Some times it does not shut off when set temp is reached and eventually I have to turn it off or change the set temp to get it to wind down. My best guess is the control card in the furnace. I'm really considering the new quite model and just replace the whole furnace or at least the interior if it will fit in my present housing. Thanks in advance.
