We switched from toyota 4-runners and bought an Avalanche as opposed to a toyota sequoia. We have had the vehicle for 6 months and it has been flawless so far.
My only complaints about the design are that the storage compartments in the fenders are not dustproof and the space over the wheel wells on the fenders are not protected from other people opening the car doors and smashing them into the side of the Avalanches fender.
Ride, power, versatility, overall comfort, large backseat, ease of conversion to large bed
protect fenders better, make the storage compartments dustproof
