Fuel Economy

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.

I have the 2nd generation LLY Duramax engine in mine and i love it. I had to replace the injectors when i bought it at 130,000 but other than that i have just been upgrading. The ride is great, the seats are comfortable, the fuel economy is good, 20-24 highway, 15-18 city, if i keep my foot out of it(hard to do with 400 HP and 600LbFt of torque on tap). I have not had any major breakdowns since owning it. The transmission did blow up at 143,000, but it was a freak electrical short that caused it to engage 2 gears at once(lots of chunks in the pan). It actually got me all the way back to the shop in limp mode which was about 25 miles, 10 of which on a logging road.
This Truck needs help!

Truck rides very rough. Truck's brakes are sluggish. Truck is 6 litre not great gas. Truck has had all kind of problems! If you have to stop fast you are in trouble. That's why this truck has been in 3 fender benders. Had to replace complete rear brakes and rear seals .
Diesel is wonderful

Traded in my 96' GMC 3/4 ton Suburban, w/ 454 Vortec engine for this new crew cab, Duramax w/ Allison transmission. Wow what a difference in towing power. Previously driving over mountins into Prescott and Payson, from the Phoenix area, we were lucky to keep up 35mph. Now, wow, 65mph over the same roads and mountains, towing the same trailer. Diesel milage is better than the gas by about 5 to 6 mpg. Wish the Suburban had this engine/trans.

I appreciate the diverse choices when purchasing vehicles but choose to pick GM d/t the ability to find anything from fast sports cars, Corvette, to tough Durmax Diesel. The current Vehicle of choice is as described above and I wouldnt tow w/out the performance of the GMC Sierra 2500 HD Durmax Diesel. Not only does the beautifully engineered design look great driving down the highway but also performs outstanding w/absolutely no problems. This is my 3rd Duramax and would recommend it to any serious driver that needs a truck w/towing capacity. Not to mention gas milege...what truck of this capacity can get
