Forest River Rockwood Ultra Light 8315BSS

I own a 2015 Flagstaff Classic super lite. I have towed it about 6000 miles so far 5,000 of them with my F150 heavy 1/2 ton and now with my Ram 2500. I have not experienced any problems in the wind and even in a little snow. It says 7500 LBS dry weight and 8700 max weight. It scales at 8400 lbs loaded. We have had no problem keeping warm down to about 15 degrees and no problem with our single 15,000 output A/C. We spent a couple of months in Fla. this past winter and in May Al. and Mississippi where the temps were near 100 and the humidity about the same. We were always comfortable. Hope this helps
