Ahh. Sounds like my wife's '08 2500HD. Love the sound of that 6 liter though.I bought the least expensive "work truck" in plain white. Hand crank windows, no remote entry, heck, no electric locks LOLA
Rubber flooring, no cruise, cheap am radio...
Everything else we added, mostly via used parts from eBay. And the paint was about a grand thanks to me painter.
I recently had to add fender flairs and a grill insert because all her girlfriends are buying Raptors. Add a little at a time whenever she makes noise about replacing it. Of course I bought it in January '09 when GM was dumping vehicles for pennies on the dollar. OTD I paid half the MSRP of the truck.
