Owning the trailer for less than 24 hours: trading it wasn't an option, at least not yet:LOL Up here, we have 6 months of winter, 6 weeks of cool spring, another 6 weeks of cool fall, leaving only 3 months of summer: LOL In the Rockies, it can get close to freezing at night, even in July. This is a Cougar Lite, not a 0°f rated Cougar. I like the floor plan, the fit/finish and all of the standard options. There was not enough flow from any vent: IMHO, Even though I got the standard reply " this is within factory specs" I am lucky to have a good dealer, who if I was willing to pay, if Keystone didn't, help me with this issue. I am going to put a larger 40K furnace in, shorten and tighten up existing 3" vent tubes, tape all possible leaking points. We will see if this "smoke us out" or at the very least, keeps ua at room temp, even at 32°f-0°c; Thanks for the replies.
