toilet plumbing design

[48_liner]

I'm looking to install a black water tank behind the axle and between the frame rails. The toilet will be against the outer wall. I'm not sure how the plumbing will go from the toilet past the frame rails and into the tank. Anyone have any solutions for me?

Thanks
Bob

No solution for that,your tank needs to be under your toilet,the toilet really doesn`t flush enough water to keep a pipe clean,so there goes elevating the toilet and offsetting the drain. Dave
