I am running 265/75/16E on an 8" wide wheel and towing is very stable. Over Thanksgiving I drove it 2700 miles with 21mpg hwy for the trip. I know I have pulled up next to a running SD in a parking lot and could not hear my 6.6 running over the SD clatter. More refined is a good way to describe the Duramax. Here is a recent comparison done by The Diesel Page between the Ford SD and the Chevy Duramax.

Since you found a nice 07 Classic, here is an earlier pull off article featuring a new 06 LBZ which is the same as the 07 Classic LBZ.

Hope these help with your decision.
