I've only been here a week, since I brought home my new Crewmax. I'm thrilled with this truck, it's like a Lexus pickup. Smooth, powerful, plush, big, best pickup I've ever owned by far. (I've owned-75 Chevy C10, 78F150 4x4, 92 F150 Supercab XLT 4x4, 95 F250 Supercab XLT powerstroke, 99 F350 Supercab XLT powerstroke). It seems many of the threads here are perceived or imagined issues with the truck, to the point of silliness. I'm starting to think that some of the posts are trolls by GM sent here to cause trouble. lack of headroom? no ground clearance? the knocking thing? I don't see any facts being put forth, only conjecture. I've owned alot of vehicles besides these trucks, and most of them were bought new, so forgive me if it sounds like alot of the flack being directed at this truck is without basis.
