This is exactly why I said, "cut the pipe in half, that is going back to the grey water tank. After fitting your toilet back in, you can put a rubber coupler with hose clamps to put that pipe back together." Actually, install the coupling before bolting everything down so that you can slip it easily over both pipe halves. Tighten the clamps after the toilet is bolted down.

That way you don't have to cut the drain pipe under the toilet. Cutting the grey water discharge pipe will allow you to just screw the toilet flange back down to the floor (where it belongs).

The toilet drain pipe (which is flared at the top) will then be free to fall into place in the flange, so that the toilet can be installed properly. Once the toilet is bolted to the floor, there will be no stress on the plumbing below the camper. Now you can deal with putting a rubber plumbers joint coupler in the grey water tank pipe and it will be all back together with no stress.

The grey water discharge pipe is what is causing the problem in the first place. The toilet drain pipe isn't too long, the grey water discharge pipe was glued into the fitting in the tank twisted wrong. That caused upward pressure on all of the rest of the plumbing.

*** FOLLOW_UP NOTE*******
You will have to reinstall your broken floor flange (just use bigger screws). Once the grey water tank pipe is cut, the toilet drain pipe (which is flared at the top) will simply slide back down into the floor flange seat and stop (the pipe won't go past the flange because of the flared end of the pipe). If you buy a new flange, you will still have to cut it, open it up around the drain pipe and screw it down to the floor. Either that, or you will have to cut the drain pipe, screw down the flange, lower the top end of the cut pipe down through the flange and recouple the 2 halves of the cut and shortened pipe. Even after all that, you will still have to cut the grey water drain pipe to get the flange to seat squarely in the flange. Trust me..... that would be 10x as much work then just cutting the grey water drain pipe and letting the toilet drain pipe fall squarely into place in the flange..
