So I looked through all the Trail Gear TV episodes the other day and noticed how awsome of a truck John Robertson has. If you've never seen it, its either a 4runner cab or a pickup cab with the back chopped off. It then goes onto an Allpro looking flatbed. Its just an idea I am tossing around right now because I need to get the priorities done first like the SAS and possible engine swap but what would it take to mount a 4runner cab to a 95 pickup frame and build a flatbed off that?

I know the flatbed is cake and I'm 80% sure the body mounts line up except the front clip. Has anyone seen any other rigs done like this?
