Traded in the caddy and picked up a 15 Silverado LTZ Z71 yesterday. Haven't been in a truck since the mid 90's so I need some schooling. Looking for a tonneau cover, tint front windows to match the rears, some kind of sub box etc. I only took a quick cell phone pick, but they all look the same. It's loaded. Is there a decent forum for these bad boys so I could get some ideas?
