Hi axle234 - While I don't have the particular model Canyon Star you refer to, I do own a 2010 3647 model which is a couple feet shorter. It drives and handles fine for a gasser and I'm confident you would be happy with either model you're looking at. As for leg room, I am 6'3" and generally have to move my seat forward when driving. The Ford chassis (F53) with the V-10 has plenty of power for most driving, flat land or mountains. Personally, I love the 3953 floor plan, probably would be my choice if I were in the market right now. Good luck in your search.
