I just put the edge/attitude in our '04 Lb7, VERY easy install, I just put a post on the site to see if there are any other recomendations or concerns. I have a friend that sells all the different aftermarket setups, (he alone does 30-35 grand/month in truck accesories) he told me the edge has the best feed back from his customers. the edge boxes have gone out in 1 out of 12 he has sold recently... (to me thats WAY high), but they unplug, and egde has been warranting them no questions asked, so its not a concern. (when they go out, it doenst leave you stranded, it just runs crummy, so you unplug it, and its back to stock) so far, im very happy with it, but its been less that 24 hours.
