The B&W turnover ball is a fabulous hitch. I installed mine in 3 hours in my driveway in march of 2002. with snow and ice and it was ccccold too. And you can build on it with the companion 5th wheel hitch. (I have both). easy to flip over the pin. and on your 2001, it doesn't require any drilling on the frame, just the cutting of a 4 inch hole in the bed( that the instructions make it easy to be dead on . )
