The 2003 are not as good 4 wheeling as the 1997.5 or 1998. Because of BTM. If I bought the 2003 I'd add front e-locker. Then you would have a truck that could follow the older Hummers. I can follow the older Hummers with my 04 H2, except for ground clearance, ctis, btm, front and rear elockers 38 inch tires, heavy duty suspension, better under body protection and deep water. Take all that stuff off and I can go any where they can!!
