I have a longbed doublecab 5.7 SR5 2wd. I traded a Silverado 2500 crewcab, and was counting on the TV ads to be accurate. The ads lead you to believe that although it is a half-ton truck, it is almost a 3/4 ton. Not even close! If you are a person who drives to the office and parks the truck, picks up some lumber on the weekend, and tows the boat to the lake on the weekend, then this is a wonderful truck. If you work out of your truck and carry heavy loads, then be prepared to be let down. It is a light duty 1/2 ton truck. The tires are rim protectors, not truck tires and can inflate to only 44 lbs, not 70lbs like a real truck tire. The suspension is soft. But I like the truck.
The transmission is better than the engine - computerized, seamless shifts, knows when to downshift. 5.7 engine is the best gas engine I have driven ever. Tow mirrors are excellent. Bucket seats w/ console are large and comfortable. A/C is very quiet. If they make a 3/4 ton, I'll buy one.
Instrument panel needs a re-design. Put real truck tires on this truck. Brakes are not linear and take some getting used to. Build a 3/4 ton and 1 ton model. A little thing, but the doors unlock themselves when the transmission is put in park, even with the engine running. I still want them locked.
