New 4" heavy duty bumper cannot fit Rhino drain hose inside

The fence post idea is interesting. I was just out looking at the RV thinking about where best to mount a PVC tube and I wondered if underneath would make more sense than on the bumper.

A tub may work also, i need to figure out with my current tubs in the storage compartment what could fit. I have used my Tetris skills from my youth to figure out an optimum storage bin setup for both storage compartments... :)
