I've helped build a few pickups with a suburban chassis--you need to rob the rear cab to frame mounts from the pickup frame,and bolt them in the correct spot after you put the cab in place and line up the front cab mounts(they line up fine with the truck cab).The wheelbase is different on a suburban,and the rear frame is slightly longer,and its not the exact same bends as a pickup frame--its a chore to put a pickup bed on a suburban frame--the body mounts on the burb are in the way,and you have to make holes in the frame for the bed.The 2 trucks I worked on were mainly for off road use only,we put a long flatbed on both to carry firewood in log lengths--another guy I now found it easier to just saw off /forums/images/graemlins/hack.gif /forums/images/graemlins/hack.gif the suburban behind the drivers door,and put the back wall of a pickup cab on it,and make it a flatbed.They haul a lot of wood! /forums/images/graemlins/crazy.gif
