I have had a lot of fun in this camper, bought it new. Use it for camping, fishing year round including ice fishing, hunting, traveling. I have used it in below zero weather many times, it's an all season camper. The air works fine but I hardly ever go where i might need it. The Cummins generator is really great. The basement storage is nice, great for fishing rods. The fridge quit 2 summers ago, had it replaced with a 3 way. The bolt that connects the slide shaft to the slide motor sheared off last winter. Pretty simple fix once I figured out the problem. After 9 years of use, I guess it was tired. The batteries are getting old, probably should be replaced. I have it on a Ford F350 with TORKLIFT tie downs. Will let the tiedowns go with the camper
