I have a 2014 XLR 27HFS. The sewer hose storage that comes with the camper will only hold the el cheapo hose they give away. You will not like using that hose, and it has a tendency to leak or break - not good. My advice is to buy a good Rhino hose and replace the round storage pipe with a 5x5 vinyl post. There are many threads on this site about the post (including one of mine).
