I've gotten that impression. Is there any noticeable help from insulation in walls/ceiling so that the furnace cycles have several minutes between them, if that makes sense. Ours is off for only a very short time if outside temp is in lower 30s and below. We have thermal windows, enclose underbelly (not heated as far as I know) but no thermal package. I don't want to pay for something in our next trailer that doesn't work.
