Thanks ROBWNY, I just looked underneath the rig and saw that there was a factory sewer hose storage underneath. I didn't see it because it was way under the rig by the axle and doesn't come to the edge of the trailer. I actually had to get on my hands and knees to see it, which means im gonna have to do the same when using it :(. My Rhinoflex hose barely fits inside, but I can't have the attachments on the hose because they wont fit in the tube. Also, I can only fit one 10' length of hose inside so I'm going to have to build another tube. I really like Barney's design. Which brings up a question for Barney, how did you attach it to the bottom of the rig?
