Mornin' all! Picked my new 22' Sierra AT4X a few weeks ago. Installed a bed cover, running boards/sliders, larger tires, tinted the front windows to match, and getting ready to install a Borla S-Type exhaust. Very happy, so far, with the truck. Looking forward to getting some solid recommendations/advice from the forum, and hopefully contributing what I can from time to time. I'll post some pics when I get some time.
