Drove down to the Dandy tonight to get the weekly ice cream allocation (fer the dawg of course)anyway I parked my 95' Silverado next to a nearly identical 95' red Chevy. Got the ice cream (for the dawg) and my smokes (the dog don't smoke). A nice lady followed me out of the store and obviously belonged to the red truck. Her truck says 4X4 on the rear fender, mine says Z71 off road. She asked me what the difference was. I told her "I suppose maybe the sticker on the fender?" I had not kept up on the chevy nomenclature having driven Fords for a number of years. So what is the difference?
