We have an avalanche with no plastic cladding. It's my wife's daily driver but it has high mileage.
She chose it because the previous owner took meticulous care of it with very detailed maintenance records.
It has been ok so far. The only issues we have had were the ac belt went, power window motors went, and bed leaked, but dealership replaced all at no cost.
It towed our 33' flat bed trailer with two loaded truck boxes, a 40 gallon gas tank full, two spar tired and 4 ATVs. From eastern CT to western PA. Did great on hills.
We like it because we can open the back up if we need extra room if we don't want to use our large tow vehicle for little projects.
