I am currently contemplating moving up from my 94 Suburban to a 00-03. While searching the net, I learned that there are Express vans with AWD. A van might actually be better for me as it would have more interior room (with all the back seats out) than a Burb. However, I need it to tow 6000lbs + and also get me into our hunting camp. It's not big time mudding or rock crawling, but it is 6 miles of off road two track ruts and rocks. How would a 1/2 ton Express with the 5.3 handle the towing and off road stuff?
