My GMC is equiped with the 8.1 liter engine and Allison 5 speed transmission. I tow a 26 foot travel trailer and cross the US frequently. The trailer weighs 7500 pounds, loaded. I have had no problems with performance and it has ample power in the mountains (Rockies). The only down side was the difference in the cost of oil changes at GM dealers. High of $32 low $17.

This is one awesome truck. We are appreciative of the creature comforts, all around visibilty, safety/security features and OnStar. I pull a 30 foot 5th wheel, (about 11000 pounds) and have been very impressed with the trucks ability and ease of maneuverability. I regret I didn't wait for a DuraMax, but I'm getting along fine without it.

For a top of the line truck that listed for over $32000 new you would think the company would put in better seats ;such as more padding in the bottom seat and go back to having the whole seat move by power not just the bottom. (this is for the cloth seat). the seats in my 1997 were more conforbly , other than the seatr it is an excellent truck.

The 6.0 engine knocks a little until warm...other than that it's ok. Lacks real pulling power, even with a 410 rear end. Tranny went out at 9700 miles. Power window regulator at 37000 miles ($500), Rotors now acting up at 47000 (all of a sudden??) Pampered truck. Goes to FL with a light trailer and back annually, othewise no strain. Hauls nothing. Looks like the 8.1 and the Allison was the way to go. Ride was real choppy from day one. I mean bouncey on an uneven road! Hang on in the rear seat! GM should be able to do MUCH better than this. They say every HD truck is made for 200K...at what expense?

Overall Good Truck. I am impressed with the sturdiness of the truck. The 6.0L has provided plenty of power with only occasionaly towing. However, the engine began knocking for the first 5 minutes on start up at about 17000 miles. GM says it's o.k. but extended the engine warranty to "make me feel better." Had to have work done on steering column as it began knocking when I hit bumps. Speaker in passenger door had to be replaced. I am now noticing some delay or slip in the transmission when the stop light turns green. A little scared where this all might lead. Don't have the Allison.
