I've now owned my Z71 for a little over a year and in general, I'm quite pleased. The engine runs beautifully and sounds as good as it did on day one. The interior and exterior look great with minimal maintenance. We only have one child, and this truck serves as the family vehicle,which it does pretty well. Frankly, with a baby seat in the middle of the back seat, safety for my infant is not a worry and it fits nicely.
Auto 4WD works fantastic in the winter. The truck drives better than a front-wheel drive car. A/C works wonderfully. Love the two-tone
Transmission can slip after coming to a stop from 60mph or above. The roof should be ribbed for strength. It can occasionally "wobble" with highway winds. I've had a constant issue with driver side door squeak. The back door seems to "wiggle loose" while driving and needs to be occasionally re-shut.
