Hey everyone. Im new to the site. Just upgraded my 06 Sierra to a new 2013 Sierra. Decided to join a forum to be able to ask around about products and issues that may arise with my new truck. At the moment I'm looking for a tonneau cover. I use my truck bed quite often but would like a tonneau cover to keep snow out the back of my truck in the winter and also to help with the gas mileage. I would like something that is easy to either flip or roll up, and once flipped or rolled up give me access to the full length of the truck bed. Any recommendations? Brands, models? Thanks for any input.
