This is a 2wd 4.7 v8 auto w/3.55 rear SLT. No problems, at 29k replaced w/17" plus size rims and tires from Laramie Ram 1500. Much better ride quality after that as well as slight increase of apx. 3/4 mpg. This is very basic engineered as a truck should be, although front end design is far superior to previous trucks. It is tough, muscle like in design. I have made a few mods such as duel exh., chip, intake, all very subtle changes. Great to park vs. full size, huge towing capability. Engine is happy to 'scream' at times. Quick for 4000 lb. truck. Excellent room inside (two huge kids fit great back there).
Engine is fantastic. Looks are cutting edge. I can scare the hell out of any truck on the road.
