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.
Favorite Features
Love the OnStar e-mail updates & MP3 connect. Only thing I've had to change is the oil & filter; have K&N air filter. Tranny fluid is still full & pink. Plenty of torque; have to be careful when road is wet.
Suggested Improvements
Stabiltrac which GM added in'08, so I'll have it next time. Can always use a little more horsepower and fuel mileage.

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?
Favorite Features
Comfort. And it's quiet. Fuel economy. Towing. Power.
Suggested Improvements
Driver side grab bar, ladder system to get into the truck bed (like the Ford) & motorized mirrors, or lowered mirrors for better visability out the sides/doorposts.

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.
Favorite Features
Firm ride, drives and pulls great with the loads I've used so far.
Suggested Improvements
More pockets/compartments. Overhead storage. In bed trailer-light hook up for 5th wheels/trailers.
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!
Favorite Features
Allison transmission is awesome and limitless power from the diesel. Very quiet on the road.
Suggested Improvements
Smaller tailpipe. People think I am trying to make a statement...

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.
Favorite Features
The brakes are real treat after my Jeep Wrangler, which had underpowered brakes and front rotors that warped consistently. The truck gets a lot of looks.
Suggested Improvements
Perhaps it is GM's policy to prevent upgrading items like cruise control and fog lamps - but for customers like me who buy a unit off the lot, I would pay a reasonable price to get the factory equipment installed by my local dealer.

Review
I purchased my GMC a few weeks ago so far so good. I had a Ford F-350 powerstroke with 7.3. The GMC is small in the inside compared to the Ford. The GMC has a lot better fuel mileage but seems to be too light to handle heavy trailers. It's not short of power it will smoke my Ford easily. My biggest complaint is lack of interior room. GM still needs to do their homework on that. The quality is not matched by Ford or Dodge in the interior and standard accessories, but I think Ford is heavier duty than GM for all out abuse on the farm or on construction sites. In about a year i can tell the truth because I know Ford can hold up. Curious to see if GMC can.
Favorite Features
6.6 Duramax and Allison is great combo very strong. Fuel mileage excellent, 15.8 in town 19.6 on highway.
Suggested Improvements
More interior room and rear air vents. No room for larger tires on front.

Review
Great truck! The Duramax towed my 31ft Airstream on a 5000 mile trip without any problems. The truck was very stable and had lots of power to spare in all situations. Gas mileage was around 12.5 mpg towing and 17 alone. I hope for better mileage after the diesel gets broken in. I expected at least some problem to show up on the brand new truck but am pleased to say everything is working perfectly.
Favorite Features
Power of the Duramax and the Allison transmission - perfect for towing.
Suggested Improvements
The one bad feature in my view is that the 2500 crew cab with short box only comes with a 26 gallon fuel tank. Not nearly enough fuel capacity for a big truck with a diesel engine especially when towing.

Review
One of the best trucks I've owned. Was looking at another brand until someone told me how good the fuel mileage was with this truck. Somewhere around 18 to 20 mpg highway driving. The 6.6 Duramax diesel/6speed Allision trans is one awesome drive train. Plenty of power to spare. Shifting is very smooth. Interior comfort is excellent. The dual zone auto temp. control, leather power bucket seats keeps comfort at the front in this vehicle.I would highly recommend this truck to anyone wanting muscle and comfort.
Favorite Features
6.6 Duramax engine,6 speed Allision trans. Interior comfort, and fuel mileage.

Cab handle on drivers side would help.

Review
I really like the bigger roomier cab on this truck. It tows my camper with ease and has lots of power to spare in the 6.0L engine. I do wish it got just a little better gas mileage but with power comes consumption. I would buy it again I like it so much.
Favorite Features
Suggested Improvements
A better console area that has a lid that closes. The console with no lid makes letting the 3rd passenger ride pretty inconvenient.
