I read a post here a while ago by a guy who replaced his tailgate window with a camper top door. I think this was on Blazer with a hand-cranked window. This sounded GREAT. My dog is an '87 with the flakey power window. Anyone out there done anything similar? Anyone out there go whole-hog and put in something more like the Side-by-side Suburban doors? That damn tailgate just sucks the joy right out of an otherwise fantastic machine.
