Once I Take the black tank off the camper its flat as can be the full length. I have another pickup and another camper if I ever need a different setup. I got this truck strictly for camping so I will probably just leave the Avion on it permanently. The Avion has small tanks anyway, I figured This is a way to gain tank size and solve the problem of raising it. I may just use one huge tank for all the waste water and black and simplify things even further.
The shower if used will need a trap and it will be below the floor , even if you eliminate the original black tank ( there was no grey tank unless one was added ).
Also keep in mind that the new tank/tanks should be vented high enough not to allow overflow .
If the camper is mounted permanently there are lots of options for plumbing .
