    Sewer hose storage?

    Hi fellow 303 RLS owners! We are proud owners a new 2018-303 ( not yet in our possession) my question is, we’re do you store your sewer hose is there a external hose housing or in the basement ? Does any one have a favorite hose or system? I’m liking the Lippert waste system.

    Try this also. the 2017 has a shorty hose holder not long enough for more than 10' to 15' of hose. There are also other threads on this "fence post" idea.

    New 303RLS owners here as well ....also still at the dealer as well awaiting slide topper install. Next time you see yours take a look just astern of the wheels on the left side. You will see a black tube mounted there - that's your sewer hose storage. I am a little concerned that it doesn't look big enough (in diameter) to hold a good quality sewer hose, such as a Rhino tho, ..... guess time will tell after I get it home.

    It's wide enough, just too short. By adding another holder, you have a long one and a short one. The fence post ones are generally 5" not 4" wide. I think I carry a 15' and a 10', not sure. Some people carry much longer lengths, problem if you are too short! "JerryR" had a nice write up on how he did his.

    The new 303's have a rather short but workable hose storage. I added an additional fence post style,next to the sewer outlet.
    Thinking about adding another.

    Our Reflection came with a short tube that only fit one length of sewer hose. I replaced it with this one which runs the full width of the RV:

    It fits two hoses and works great! Not cheap though :-(

    They are all pretty much external housings somewhere under the frame depending on trailer model (front or towards back). The basement storage idea is the hose coiled up in a plastic tub, but that's not the preferred method (smell, air flow etc.)........in an answer to your original question.

    I like the fence post idea, I used pvc & build a clamp on my past camper a bit heavier but worked great.

    The tube supplied by GD on my 2018 303 holds my 20’ Rhino hose (collapsed) with quick connectors and elbow with room to spare. I have a 10’ extension in case I need it. It lays in the black plastic tray in the compartment with caps on after a good rinse out.
