I've owned my 2009 Chevy Avalanche for ~6 months and have thoroughly enjoyed driving this truck. The ride height is great and the ride is very smooth. The four-wheel drive has worked well in the limited snow / slush we've had, didn't slide around at all. Good acceleration and power. A bit thirsty, but not much more so than was my Montero Sport.
