If you're a fan of the GMC Sierra HD, and Chevy Silverado HD for that matter, but think you need four-wheel drive, more chrome and LEDs, then look no further than the Sierra All Terrain HD. It's like a really big field office with a backup camera and a Wi-Fi hotspot.

Here's what GMC's VP of sales and marketing Duncan Aldred said in the Sierra's press release:

The new 2015 GMC Sierra HD lineup helps customers tackle tough jobs more comfortably, and with the new All Terrain HD, they can do it with greater style. Equally comfortable whether it's a night on the town or traversing a remote job site, it has all the capability that customers demand from a GMC heavy-duty truck on the job.

Well, that says it all. Because the All Terrain model, on sale this summer, packs in the Z71 Off-Road package with Rancho shocks, hill descent control and a skid plate. Available in SLE, SLT and Denali models, the upper trims also get these monster power-folding side mirrors.


But don't forget the badges. In keeping with big truck tradition, this Sierra HD reminds you it's ALL TERRAIN everywhere.
