Great Diesel Truck
Tom, 12/22/2015
2015 GMC Sierra 2500HD SLT 4dr Double Cab 4WD LB (6.0L 8cyl 6A)
Bought this SLT model after trading in a 13 2500 HD Denali. Needed to pull a 16000 lb Fiver camper. This Pickup has extreme power and smooth shifting. Thought about getting a single rear tire toner till I realized the only difference was an extra leaf spring is all. I had automatic step sides that come down when you open the door and that made access in and out easy even the wife … enjoys it. I have 13000 on it now. I guess I don't see any issue with the headlights seem the same although I did notice at the parts counter upgraded bulbs on the counter so maybe that fixed the issue. I especially like the bright lights in the side mirrors for backing up at night. No problems with the leather or accessories, I did get extended warranty just in case. mileage varies about 8 mph pulling the camper and 17 mpg on the highway not pulling town about 15. Seems like a great pickup more to come.
