Recieved a video and info on the Coleman mobile home furnaces . I already knew they were a bad system, but mainly only in real cold climate like Minnesota. Exhaust probs take out the Pipe, and heat exc. (condensate issues)

So I watch this video tonight, what a a pain. Inspecting these units, and putting in a shield if they arent cracked, and installing a new one real pita if they are. Anyone else watch this video or hear about this. We are lining up the calls for this right now, looks like my next coupkle months are lined up. Oh well its work.
