Bought deisel truck for camper and boat. this truck goes over mountain passes like the load isn't there, 15,000lbs. I bought an aftermarket engine program to increase performance, and with this chip I get 20mpg empty, 15mpg with boat or camper, 13mpg with boat and camper. Programer takes 5 minutes and allows me to program for specific loads or to put it back to stock settings, recommend this. There has not been 1 problem with truck and have already put on 12,000 miles in the first 4 months. Very happy customer.
Piece of crap

This was the worst vehicle i ever had. It broke down right as i was pulling out of the dealership. The dealership then actually charged me for towing it the 10 feet to the service area!! Turns out the axle was faulty. They also found that the radiator leaked too.

It's a beautiful truck, feels like your riding in luxury. We have the TV/DVD package and that works great for our 4 kids who fit comfortably in the back on long trips. Good on gas for something that size, always runs and drives great. Have also used it to pull out the tractor when it got buried plowing the field, was not a problem it came right out and the truck barely had to try. Also pulled out a boat hauler that was stuck in a field, no limit to this truck.
I will never own a GMC product again

It is no wonder GMC's cannot compete with Ford any longer. I was sent an email to update this -12/29/17. Not sure why! Still the same title for sure but now worse, entire dashboard is not functional, speedo does not work, all other gages peg out when starting the truck. At least it is running-mostly. I have to hand pump the diesel filter to get the truck to start. Happens about once a month or so. (no it is not standar maintenance issue). Replacing the batteries annually now (seems something is draining them when I am not looking!) I have received a call from Cust support about the dealer charge offering to reimburse some payment. I would have even considered changing my review if he would have helped. Then he disappeared! From the Dealer using my truck to tow the owners horse trailer (when turned in for maintenance) and adding 100 miles to it...to the more than $3000 I had to put into the electrical within 3 months-to the instrument panel stopping to work (speedo, then oil pressure, then battery-which comes and goes) $900 fix it so I just use a GPS for my speedo-to the rattle in the steering because of design issue always going out....to the electric seat positioning clicking 7-8 times before settling into place-to now the heater/AC blower stopped working and a cost of $750 to fix it at PEP Boys. Thanks to youtube the heater fix will only cost me $150 in parts. (my friend just had the same thing happen to his Tahoe and had to pay $750) The heater went out again in a couple of weeks. replace resistor again, heater stopped again! Either this truck is a lemon OR my favorite GMC's are on their way out of business. (I am in Quality management and would not have allowed anything close to this happening where I work)

This is my 2nd GM diesel truck and it has operated flawlessly since delivery. The power and accelleration for a big truck makes it fun to drive. I tow a 14000 lb 5th wheel and can pass with ease going over the mountains. The mileage is about 10mpg with the trailer and running 65, without it runs about 18-19 mpg on the highway.
