Used 6” PVC (painted) with a conduit holder cap kit to come up with a larger stinky slinky tube. I wanted something I could store a 10’ & 15’ sewer hose in with out forcing the door shut on the Valterra storage tube. Using the Valterra tube for two 10’ because of the two gray water tank set up. The primary tube is now located near the main drain dump valves instead of under the slide.
And unintended benefit for the new tube is that it acts as a deflection point for the exposed drain pipes in the event of road debris.
