My first diesel - 2007 GMC Sierra 2500HD
By cdietz - March 14 - 7:00 amI never had a diesel before but my prior experience with gas trucks was tainted with getting 13-15 mpg. So I opted for the diesel with the allison. Wow. I get 19mpg average and on highway trips I average 21.5. I put about 31000 on it so far in 10 months of ownership and I have no complaints. The true genius of this whole setup is the transmission. In tow/haul mode it downshifts for you when you brake while matching revs. Really saves the brakes and instills total confidence in pulling heavy loads - skid steers, tractors, trailers full of blocks, etc. I get about 15-16mpg while towing on the highway. Great truck!

The Best Ive Seen - 2007 GMC Sierra 2500HD
By MOC - November 21 - 9:50 pmI have put 70,000 miles on this truck, and it is by far one of the best vehicles I have ever owned. Any negatives I have seen on here were in reference to the SLE interiors or the Gas Engine and its transmission. The truck handles very well and can pull anything you can imagine. The 6.6L Diesel and its transmission get excellent mileage for a truck this size. I get 22mpg on a 55mph highway and 19mpg on 70mph highway. City mileage is around 14mpg(with lots of stoplights). I dont think you could find a quieter diesel thats more comfortable, more powerful, and tougher than this truck. The seats do have good lumbar support in the SLT package. I really highly recommend this truck.

Work Truck Z82 Priceless - 2007 GMC Sierra 2500HD
By rendog - July 28 - 5:23 amBest truck for the buck. 98% of this truck life has been pulling a 3.5ton trailer on the hills of western PA. Its like an old hound dog ready to work. Its powerful and comfortable for the wife and kids. Handles like a long Camaro. I get about 18.8mpg @ 72mph and about 13 combined when towing. Rented a diesel but it has too much torque for stop & go. Get props every time I stop for its true work look. Only 2 problems, TPMS and an exhaust gasket failed.

Love my Duramax! - 2007 GMC Sierra 2500HD
By dozergirl11 - June 1 - 10:56 amI bought this truck with over 100k miles on it, but was obviously well taken care of, as it is now. I have pulled several trailers already that stretch the written towing capabilities, but she has pulled them all just fine with no squatting, and the tow/haul option does really well even with the larger trailers If I was going to buy a truck again, Id buy the same one. The SLE2 is nice inside and out, with my favorite part of the exterior being the cab lights. They just make the truck look sharp!

2500HD - 2007 GMC Sierra 2500HD
By 2500HD - September 29 - 9:16 amAt first I didnt like the styling, because it looks like a Ford. I chose the 6L gasoline engine in the 2500HD to avoid active fuel management in the 5.3L engine. With only occasional towing, the gasoline motor is a good choice for acceleration with less maintainence. The gas mileage is only slightly worse than I am used to with my Jeep Wrangler. The brakes are really powerful once broken in. Comfort on the open road is great. I bought the vehicle on the internet at great price, but it came without cruise control. I asked the local dealer if he could add it and they said "no". On my Wrangler, it was no problem because the wiring is already there, but GM doesnt do this.
