I thought long and hard before buying this vehicle. I compared it to the Cadillac EXT, Toyota Tundra Ltd, Ford F-150 King Ranch, Dodge TD, GMC 2500 Duramax TD w/ Allison6spd. In the end, all those other vehicles were just trucks. If what you really want is a truck, then buy the GMC or the Tundra, in my opinion. If what you want is really a very nice SUV with lots of bells & whistles that also doubles as a pickup truck, then the Avalanche is for you as it was for me. I have every toy you can get on this LTZ and I suggest you either get the LTZ or the LT3 w/Z71. No LTZ ride leveling on the LT3 though. No 4x4 in the Caddy available.
Midgate: no one else has this in a full-size pickup except the Cadillac EXT, which is the Avalanche LTZ w/ a slightly different body, no 4x4 & $10k more. Generous front cabin, big covered rear bed, smooth handling, spacious tool compartments, OnStar! they e-mail reports! Elec folding mirrors.
Larger glove box; the owner's manual won't fit. Optional console dividers. Quieter engine. 6 speed Allison auto transmission. Better mileage. Optional diesel. More rear knee room. Place for rear headphones. Console shift intead of on the steering column. Elec. rear window, easier tire replacement.
