"'05, Z-71, 2-WD, EXT CAB. Good truck all around. The two most troubling things with this truck is its awful turning radius and that there is no key lock on the passenger side door, get power locks for certain! Performance is satisfactory and I especially like the stiff suspension of the off-road package. I've had to have the AC control replaced and a brake light socket replaced. I average between 17-20 MPG with combined city-hwy driving, 19-21 hwy alone."
