Just think of a long wheelbase Jeep, about 4 ft wider, with no top, and thats a HMMWV. But, they are pretty darned fun, for a play toy. With overall gearing in the diffs/hubs in the high 5.xx they are not a highway vehicle at all. An OD tranny would cure that. Not much power, but I belive more power would start breaking drivelines. They dont ride well, 998s arent bad, any of the HD suspension models will break your back. Legroom for a tall person is little. Heat, they have no insulation whatsoever. But hey, its a overgrown Jeep right? Just flip the windshield down, andl go just about anywhere it'll fit. And thats what its all about. Id have one just for that reason. You gotta look at what you are wanting it for.

PS, with it being a AWD vehicle, combined with the width, its pretty wicked on high speed dirt roads/trails! You cant get them to slide off the road!
