2006 Chevrolet Avalanche LS 1500 4dr Crew Cab 4WD SB (5.3L 8cyl 4A)
I have driven my Avalanche for the past seven months, putting 6000 miles on it. During this time, it has run flawlessly, been a very comfortable vehicle to ride in, and a vehicle with enough power to get it up and going. It can hold its own on the highway, running 55 mph or 80 mph. At the higher speeds, I have found it to still have reserve power to make it move if need be. Towing a trailer is tolerated well by the 5.3 liter engine. I have found it to tow very well and brakeing is great. My avalanche will stop very well on its own and equally well with towing a trailer. In short, I love my Avalanche. It drives and rides like a car but has the built of a truck.
Power seats, heated seats, air conditioning, all are great and work well.
I would like to see Chevrolet tweek the motor a bit so as to get better gas mileage and more power.
