This is my 2nd avalanche. I have owned a 2001 Dodge Ram and a 2004 Ford F150 and a 2006 Avlanche. This one is waaayyy better than all of them. I had a few issues (electrical) with the 2006 but so far nothing wrong with this one. Interior and exterior are much better and the suspension and engine are much smoother. Overall this is a great truck.
All of it! Bluetooth, sunroof, xm radio, cargo area that opens up, roominess, ride quality...
Center console is a bit too big. Gas mileage could probably be a bit better.
