For full time cold weather camping I would say great things about Mobile Suites. I have an 05 and it is holding up quite well. Best insulated 5er made, 3 1/4 inch walls. I forget the R values but they are good and we stay comfortable in cold weather. I do my own work too and I've not had it in the shop and we're in our 6th year. I had a cardinal before this and it was OK but not built anything like the MS. This is solid, and built to last a long time. would not pay what a new one costs ($100,000 plus) but there are used on the market at attractive prices. In fact there is a lady here in the campground who's husband died last year and she is selling an 08 or 09 (not sure which) 36 TK3 at a very attractive price (around 30K). That's just an example, I see others advertised from time to time. Hope this helps.
