KBB.com Review
Kbb.com Expert Rating
If you need to tow or haul big loads, a compact pickup just won’t do the job. The 2012 GMC Sierra 1500 truck offers a wide range of trims, from basic Work Truck to the ultra-luxurious Denali, while those seeking better fuel economy can chose the 23-mpg Hybrid model or the 22-mpg XFE.
If you don’t have big towing and big hauling needs, you don’t really need a big truck. A Toyota Tacoma, Nissan Frontier or even the GMC Canyon can probably fit your needs and save you some big bucks.
