I have a super cab with a 6.2. I think part of the reason other trucks are faster is the 35 inch tires. I have smashed the front (should have gone faster, or slower over the first jump), I have slight frame bending, but only at the impact point. I have hit the rev limiter, once on road, twice off. I have driven across many states on multi week trips. The truck is super comfortable. Has plenty of power and brakes to tow. However, it has a low weight capacity, so don't expect to load the truck and put a nose heavy trailer on it. There are two problems with the truck. One is that it is so comfortable off road at speed. If you drive where other people are you will have to pass them. Why people buy jeeps or trucks and drive down perfectly good dirt roads at 15 mph is beyond me, but good luck passing them. If you are on a super rough, rocky road, you will destroy a set of rear tires very quickly. (3 hours seemed to remove half the tread blocks of the stock BFG's) The other problem is that the truck is super wide. A problem when your parking, but terrifying if you weren't born in Colorado and your going down a jeep trail on a cliff. Get one, you won't regret it.
