The Avalanche is fun to drive. A definite head turner. The dash layout is easy to use and very nice looking, much more so than other crew cab trucks. If you are getting this truck definitely get the leather seats and back up camera. The mid-gate is very easy to use with no learning curve. However, you will be spending more money at the pump.
Leather seats, Mid-gate, Boses sound system and body styling. The 6.0 sounds great too.
The car mats are worst I have ever had on a vehicle. Make the rear seats fold down instead of forward to allow the front seats to stay back for more driving comfort when mid gate down.
