Thanks for the great idea and post!
Until now I have been storing the hose in a rubbermaid bin in the front compartment.
I was not able to find a PVC pipe larger than 4" at Home Depot. I called a plumbing supply house and for 5" with all fittings needed would have been about $80.00.
So I looked online and C-World had them on clearance for less than half that price ($40 delivered).
I installed it to the back side of the hitch and it works perfectly.
