I paid a little less for my Starcraft and gutted the whole thing. My purpose was to build out a true winter-ready trailer. In the process, I was able to design the layout to more accomodate my use. I spent about seven times more than I paid for the rig in restoration costs. I will pay 1/7 in energy costs for heating and cooling in the future and will be comfortable while doing it.
I have yet to find a TT that is truly winter-ready. Some come close like the Arctic Fox and Bigffoot line but the physics of the dimensions and mfg.'s bean counting all set limits on what's done. Besides insulation, the state-of-the-art RV furnaces are pathetic. Noisy, inefficient, poorly engineered, and power hungry are a few of the words that come to mind.
You can look through my rebuild thread that is listed in my signature line to see what kind of antics transpired in the Cowboy/Hilton.
