1. Powerful engines 

Whether you’re off-roading, hauling compost around a farm, or towing a trailer, you need a powerful truck. The 2015 GMC Sierra 1500 can deliver. The pickup comes standard with a 285-hp 4.3L V6.

With the 5.3L V8 the Sierra can tow up to 11,200 pounds when properly equipped.
For the most towing capacity, choose the 6.2L V8, which can tow up to 12,000 pounds when properly equipped.
 

3. Upscale trim 

You’re not afraid to work hard, but you also enjoy being comfortable at the end of the day. The 2015 GMC Sierra 1500 can strike that balance, especially with the available Denali trim. That trim comes standard with a V8 engine, heated and ventilated leather seats, a heated steering wheel, a Bose® audio system, and much more.  

4. Off-road ready 

If you spend lots of time camping or four-wheel driving on dirt roads, choose a 2015 GMC Sierra 1500 with the Z71 package, available on the SLE and SLT trims.
