Im taking delivery of my first GMC truck Wednesday. Its an 08 SLT crewcab, duramax... had them install the Denali grill...few extras... but I need some suggestions on wheels and tires. First off if I want to run 35's do I need to lift the front? If so what is the easist way. Also, are all teh 8 lug (Chevy, Ford and GMC) lug patterns the same? Do I need to ask for a certain setbad/offest? Suggestion for a roll up bed cover.....
