I have a Coachmen Nova 20RB Li3. I added a sewer hose storage tube under the RV attached to the underside of the running board. There were already mounting holes on the storage tube. I had to drill a few holes in the supporting brackets for the running board. This gives me an extra 10' of hose and it has come in handy in a recent trip to Tennessee. The storage unit cost $55.00 on Amazon. It is easy to get to and it is out of the way (see photo).
