we have over 7000miles on our, it's almost 3 years old. I'm 6'2 and have no problem with the bed length (there is an after marker 4" insert you add to the head before bed to make it longer)
I've stayed in it in the really cold weather with snow and only ran an electric heater and was comfortable, my windows only sometimes sweat in the summer on really humid days with the A/C running . . . . we love ours, but the best thing about this size is, campgrounds always have a site you can fit in
we are planning a trip from Va to the Grand Canyon and back
Have fun, they're nice units
