Love my Duramax!

2007 GMC Sierra 2500HD SLE2 4dr Crew Cab 4WD SB (6.0L 8cyl 6A)

Review

I 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, I'd 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!

Work Truck Z82 Priceless

2007 GMC Sierra 2500HD Work Truck 4dr Extended Cab LB (6.0L 8cyl 6A)

Review

Best 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.

The Best I've Seen

2007 GMC Sierra 2500HD SLT 4dr Crew Cab 4WD SB (6.0L 8cyl 6A)

Review

I 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 don't 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.

GM has lowered its standards!

Review

This truck has wasted tons of my time and hard earned money. It seems the only things that have not failed yet are the engine/tranny. I also own a 2002 of the same model that I find to be 100X better quality. These are just a fraction of my complaints/problems I have dealt with on my 2007 sierra 2500hd (these issues surfaces with under 40k on unit)>>Exhaust failure, idler/pitman arm failure, hvac problems, bad factory rim, leaking oil/tranny cooler lines, cruise control works when it wants to, thin flimsy body panels, 4wd disengagement issues, tailgate handle failure, bad airbag wiring harness, door hinge failure......I have always considered GM the best that the USA can offer..Not anymore!

2007 GMC Sierra 2500HD Work Truck 4dr Extended Cab 4WD LB (6.0L 8cyl 6A)

Review

In "07 I needed a truck to tow a 7000lb 14x9x9 box trailer in western PA. I test drove 'em all and fell in love with a Ford until I learned GM had the most torque, hp & mpg. Found a GMC L82 with all towing packages. I tow 5 days a week and avg 9.5mpg city and 15 on the hwy at 62mph or 2k rpm, above 65 mph the aero drag zaps the mileage to 10.5. The PA hills takes another mpg. Without my trailer I get 15 city and 21.5 hwy. I love the performance and the bucket style seats, it feels like a Camaro on steroids. Get compliments every where I go and with 30K miles I've been everywhere.

Very Powerful. Very Comfortable

Review

I have been driving my truck for about a year & a half. I was excited at first because it was new. Now I am still excited! The Duramax/Allison is a just a great design. There is so much power for towing. This truck should come with a warning light reminding you that a trailer is attached because you will forget that it's there! No more "white knuckle" driving while towing, built in brake controller works really well. This is just flat out awesome! The seats are like flying 1st class, interior is much improved. SLT has all the goodies, more like a luxury car, except it's a truck. Why have a car anymore?

2007 GMC Sierra 2500HD Work Truck 4dr Extended Cab SB (6.0L 8cyl 6A)

Review

Bought the 6.0ltr WT version two weeks before leaving Maryland. Installed cruise control and hauled 5500 lbs on a 16ft tandem trailer and 1000 lbs in the bed. Averaged 16mpg on Hwy after tuning with the Diablo Predator using 87 octane gas. I have the 4:10 HD posi-lock rear. I average 12-13 mph in town. I would have liked the 6spd Allison transmission.

My first diesel

2007 GMC Sierra 2500HD SLE2 4dr Extended Cab SB (6.0L 8cyl 6A)

Review

I 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!

2007 GMC Sierra 2500HD Work Truck 2dr Regular Cab LB (6.0L 8cyl 6A)

Review

At first I didn't 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 doesn't do this.
