if you have room, you can open up the end and add another piece of pipe and a plug with holes in it for drainage and then be able to put 2 10 foot sewer hoses in it.
i had one like that on my tuscany and it got KNOCKED off or fell off some wheres . it was there when we left a cg, then it was not when we stopped at a rest area a few hundred miles down the road. I dont remember running over it, so maybe it slid out under and scared the crap out of a following vehicle
so i made a new one that hangs off basement floor and allows me to carry (2) 20 foot built up hoses.
