2005 Chevrolet Avalanche 1500 4dr Crew Cab LS 4WD (5.3L 8cyl 4A)
I love my truck. I often sleep in it when I'm in between jobs. It's the only truck I ever considered buying. I waited 3 years to buy and it was well worth the wait. Although, it has a rattle in the engine compartment. But I still love my truck. I've heard others traded theirs in or got rid of it because of the noise. I love my truck and I'm keeping it for life. I may get a sports car (of course a Chevy) in the future and I'm still keeping my truck.
The whole truck! Since I have to name a favorite feature, I would say the cooler and storage compartments.
Get rid of the engine noise. It's a rattle in the engine compartment not the engine itself.
