I just joined this site, but I've owned my Silverado sinec last November. Believe it or not, I purchased mine direct from the factory while floating in the middle of the persian gulf. Saved almost 8 grand doing it that way. I have a 2006 Silverado 2500HD LS Ext. Cab (8 ft bed) V8 8.1L with an Allison Transmission Tow Package and the works. Just put Nerf bars on it, and got my bed Linex'd a week after I got it. Getting my wheel wells linex'd Friday and a flomaster exhaust in a couple weeks. I love the Bowtie. I'll never buy anything else agian.
