Have you looked at the Tomcar? Not 4 wheel drive but worth a look at. They sit lower with more travel and clearance. And I dont know what is available for hand controls for the other UTV's but I know Tomcar has them. Check out a place called Toy Junkies in Arizona. They seem to be pretty tough. Matter of fact two " wheel chair users" ran one in the baja 1000 and finished and I believe the machine was stock.
