I need to repair a rusty floor. My entire cab has "sunk and is sitting on the frame. The floor, just about where my feet rest is bulged up all the way from one side to the other. The rocker panels are split at the peak of this bulge. About 4-6 inches from the front post. I have done a lot of research and watched YouTube videos on replacing various floor pan parts/pieces. My first thought was an entire floor pan replacement but I don't have the garage or skill set to take that on. My next option is to replace the rockers and the front pans. I think I have enough good floor to weld in pieces.

Just to help me understand how the whole thing works, is the cab really supported by the floor pans or does the floor supports dissipate the weight to the side structures of the cab.

I am trying to wrap my mind around how the floor pan supports the cab without some more substantial framework.
