Purchased with 7000 miles on clock to tow my 33 ft.Fifth Wheel touring USA for eventual shipping to Australia for touring Australia with fifth wheel also shipped home. Extremely happy with incredible power from 8.1 L/Allison. Great ride even on our sub-standard roads. I cannot complain about 7 mpg towing over 10000 lbs. Love this truck!! Big size a problem in city driving/parking but excellent in purpose truck was bought for-towing.
I'm a grandmother and use my truck to haul grandkids to the rodeos, get hay, and just general travel. It is the most comfortable truck that I have ever driven. Mechanically we have had only minor problems and it has over 170,000 miles on it. I can't really think of anything I don't like about it. If it ever gets replaces it will be with another Chevy 1-ton. It will pull anything I've put behind it and is extremely reliable on the road. Nothing but a Chevy for me!
Transmission position sensor failed just out of warranty. Truck starting shutting off while driving at 40K. GM no help. Found online info re: bad crank position sensor and replaced to fix. Both problems known to happen on other trucks. Exhaust stud broke and flange warped. Tailgate latch rusted inside gate and does not catch. Transmission slipping after stop and go. Toyota went 3 times as far with no problems.
