I mounted a storage tube under the trailer on the frame. I'm thinking a summer project will be to cut out the tube Jayco installed and mount a longer and larger one that actually fits a hose. If you look under the bed you will see the Jayco mounted tube, it looks like it would be an easy project to modify the original one to actually work.
