Been a GM guy from day one. My first vehicle was a 1965 Pontiac and have owned numerous GM's over the years. We currently own a Chev HHR and most recently a 2010 GMC Sierra 4x4. She's got a 3.64 hd rear axel and came with the HD towing package. She's an SLE with a short box with a sprayed in lines I had done right at the get go. Also had her given the full GM protection package so now she's kprotected three ways to Sunday. We love the spacious interior and of course OnStar is a must for us. Looking for ideas on good mud and snow radials that are also quiet on the road, because I plan on changing out the originals this fall. The fact that she can pull a max of 9500 pounds makes it the perfect vehicle to tow our 6800 pound (dry) 33 foot travel trailer. That was a sprayed in box liner.... Well that's about all for now. I'm in Calgary, Alberta, Canada right beside the Rocky Mountains, just the place to own a GMC Sierra.
