I was looking at 07 Silverado crewcabs. I did some research and realized that the new Silverado does not have 4 wheels disc brakes (the 00 did)a nd a long list of stuff that I wanted (XM, steering wheel mounted controls, 5.3V8, alloys, etc) were standard on the Avalanche, but optional on the regular pickups. Additionally, there's no provision on the regular pickup for securing the cargo bed. I bought the Avalanche LT1 with Bose and locking differential, all the stuff I wanted, without a bunch of stuff I couldn't care about. The styling is great and the ride is super comfy. Gas mileage is about what you would expect for a 5500 lb vehicle...about 14-15 in the city, 20- 21 on the road.
Great styling, super comfy ride, wheel mounted controls, removable hard cargo cover
Super heavy vehicle=not so hot gas mileage, should have 6 speed tranny
