I've had the Avalanche for about 2 weeks now and I am enjoying the truck thoroughly. Ride is quiet and refined, especially compared to the pick-up it replaced. Acceleration was a pleasant surprise. Despite it's size, I've had no problem maneuvering the vehicle in tight places so far. I do feel the back up camera is mandatory, as I find it essential when going in reverse. Fuel economy is what I expected, but still is actually slightly improved over my smaller former vehicle which I attribute to the 8/4 cyl highway cruise feature, and the ability to run in 2WD except when on-demand 4WD is needed. In short, I think this is the beginning of a beautiful relationship! :-D
I really like the lockable rear fender storage compartments on both sides of the bed. Very handy out-of-the-way stowage.
If GM engineers could figure out a way to make the midgate follow the 60/40 split of the rear seats that would add to the versatility of the vehicle - so that you could cart long items on one side and still have room for 1 passenger in the back. Would like to see mid-bed tie-downs added.
