As I bring my recently acquired '06 GMC 3500 box van up to a better state of mechanical condition, I seem unable to find a go-to web forum for general mechanical/electrical/misc info on these vans. Not wanting to clutter up the forum here with a question that's likely already been asked and answered elsewhere, I wonder if anyone has a recommendation for an active and generally accurate place where Chevy & GMC van owners hang out. Surely if owners of Chrysler minivans can be enthusiastic enough to have their own forum, then there should be one for the full-size GMC vans. Thanks for any leads, and here's a photo from my trip out in the van, hanging out while my daughter was doing horse show stuff.
