I just traded in my 2001 for a new 2005 - 3500 SLT quad cab, long bed, will pick up on Friday after the bedliner, B&W turnoverball hitch and in bed 6 pin connector installed. Since I am moving to southern Arizona I went with the 2WD for more clearance on my gooseneck trailer. Anything special I should look out for while I am breaking her in? IS ther a blow-by hose that needs to be re-routed?
