Great truck and drivebility. Seat is somewhat comfortable but supportive for 10hour trips. I do recommend the LS package for it more convinient for over all comfort. Great engines 5.3 and 6.0. both deliver about the same fuel efficiency - I get 350 miles on 22 gallons. I would prefer a more efficent truck and it amazes me that all these car maker are dragging their feet on delivering these type of vehicles.
More diesel engines, more efficient engines. spit bench seat in the back. better brakes perhaps 2 caliper front disk bakes.
