I've had my 2500HD for just under a year now and I LOVE it. The only problem I really have is its fuel economy. I average around 14 mpg, but where it lacks fuel economy it makes up for it in power. I haul around a skidsteer on a 14 ft open trailer. The skidsteer weighs more then my truck but still no problems pulling it. The fuel economy doesn't really change weather your hauling or not. I just purchased an SLR performance chip that should do the trick. This truck is perfect for anyone with the money to pay for gas.
The interior is amazing. Comfortable enough to live in. Plus I got the BOSE stereo package and I love to listen to my rock with these banging speakers.
The torque and power of the 8.1L is incredible, but be aware at the gas pump. An average of 9.1 mpg will be all you'll get. Towing large campers or trailers is no trouble what-so- ever. Especially in lower range gears the 8.1L begs for more. All around I love the truck, including a great interior and stock stereo.
Power, comfort, heated seats
Mileage gain of any would be great. GM needs to get on the ball with some reliability issues.
Only service problem was the Service
4WD Problem as well. New module fixed
problem. No other problems since. I
found the ride to be very comfortable
especially for a 3/4 ton. The room
inside accomodates the family and kids
with room to spare. 6 adults can ride
in comfort with good leg and shoulder
room. Milage is great for the power
and weight. My average milage to-date
is about 19 mpg over 17000 miles. The
transmission is absolutely incredible
and is what makes this truck
exceptional. It handles heavy trailers
with ease. I have yet to use all the
power the Dmax puts out. It is without
a doubt the best truck I have owned.
Power of the Duramax. The smooth
Allison tranmission and especially the
tow/haul mode when pulling a trailer.
Overall drivability ride and quietness
especially with a diesel. Milage.
Under the hood light. Convience lights
under the dash and lumbar support.
Minor really with the package as a whole
This duramax is bad to the bone added
bully dog 75 hp system to the truck now

thought Colarado never missed a lick
passed everything on the road and still
averaged 13.7 mpg. Truck will white

great performance and great fuel milage
change the front bumper so you can add
larger tires without having to modify
