Sorry for the big attachment. All stock. 2007 Sierra 2500 SLE1 Ext Cab Long Bed (for the toys), 2007 Sierra 1500 SLE1 Crew Cab (hers), 2004 Yukon SLT (for me and the dogs). Incidentally, the 3/4 ton is up for sale, as I have a shot at a great deal on a 2011 Sierra 2500 SLT Crew Cab (gotta sell the old one, first), and the Yukon was in a wreck on 04 October, and it's still in the shop getting repaired (a lady ran a stop sign and I t-boned her).
