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!

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.

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.
Clean GMC

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.

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.

This truck is by far the best combination of utility, comfort, and performance I have experienced. I love the truck and highly recommend it to anyone in the market for a new pickup.
Very surprised!

Took a look at the new F250 King Ranch and was wow'd by smooth leather and exterior design. Was turned off though by the interior setup. Engine had a horrible setup and high turbo squeal as well. The GMC SLT has supple and comfortable seats, but the leather isn't as soft as the Ford KR. The look and feel of everything is great though. There aren't many cheap 'looking' parts. The setup inside and out were well thought of. Also, the Duramax and Allison are tried and true. 4X4 works great and is rather easy to jump in and out of. The power is equal to the previous years model. I say this because a lot of talk is going on regarding the EPA constrictions. Great purchase!

Check exhaust manifold bolts 80% of these trucks will have this problem no recall on this issue will not pass EPA tests in most states!
