I'm trying to determine what all the weight ratings for my Suburban are. I've looked at the door sticker, and it gives me the GVWR and the GAWR, but I also need to determine what the GCWR is. I'm looking to pull my trailer and I am not quite sure if I'm in the weight limits. I also checked the owners manual for these ratings and haven't found it. I've found some scans of the old brochures for the truck on the net, but I don't have any definitive "official" numbers. The Suburban in question is a 1991 Chevy Suburban R1500 with the 5.7L; listed in my signature. It has the factory 3.08 rear gears and I think that's severely limiting my weight capacity compared to the same truck with say 3.73s. Thanks as always guys!
