well the wheels are ugly as sin no doubt...but the doors would work awsome on the trail.
Just imagine how easy it would be to get out when your stopped close to a tree or a huge rock. The door going up is going to save it swinging into the obstruction.
plus in really deep mud. when you stall you wouldent have to lean against the door to get it open because the water pressure outside, it would just go right up just as easy as normal
...hey might be a life saving feature if you ran off a trail into a river or lake.
