I have had excellent service from this
vehicle in its' first 25,000 miles.
I'm averaging about 14.9 mpg. On a
long highway run it will go to 16mpg.
I have had two minor issues fixed under
warranty. Exhaust resonance, and a
steering wheel "clunk". Both taken
care of. I have 3 boys and we all go
camping a lot. It hardly even knows it
is pulling a camper and everyone has
plenty of room. Rear seat passengers
have their own heat and a/c vents for
comfort. The ride smooths out once the
truck is loaded a bit so the camping
trips are a real pleasure.
When I bought this truck, it was for the purpose of pulling a 5th wheel RV and an enclosed snowmobile trailer. Most all towing would be in the mountains. I have alway driven GM trucks, so I was already use to the body style and interior, both of which I love. However, this is my first GMC. Ride is good for a 3/4 ton, power was good, although I knew I could better it later. Has the typical piston slap of this era of Vortec engines, but has not caused any problems. I run Amsoil synthetic oil, I change the filter every 5000 and the oil every 10,000.
I really only have one gripe about the best truck I've ever owned and that's this: GM will not recall a 6.0 for a oil pump seal that causes the oil to airiate and leaves the owner with the impression that there's a collapsed lifter. Anyone else hear that annoying ticking? Check the GM service records and you'll see that its a 300.00 fix/maybe kind of thing.
