I have a 1990 V1500 Suburban that is currently being modified...completely. I had planned to just box the original frame, but if I can get a heavier frame to start with I would like to do that. My question is: What GM vehicles (trucks) have the same frame dimensions besides, of course, the 3/4 ton Suburbans? I have no problem moving or adding brackets. The vehicle is to be used for hunting/fishing/towing, not extreme rockcrawling. Any information would be appreciated.
