Sewer Hose Storage – Installing the SuperSlider in Our EKKO

This post may contain affiliate links.

Sewer hose storage is always kind of an issue with RVs.  You need it reasonably accessible, but you don’t necessarily want to store it “with” anything – especially not your fresh water hookups!  Well, it took me a little while, but I finally came up with a solution for sewer hose storage in our new Winnebago EKKO, Number One.  Here it is!


We had actually seen and made a video about the Super Tube years ago.  You can find that video here.  Ever since then, I had wanted one, but never could find a place to install one in our Class B, Lance.  Now that we have an EKKO, there were more options for where to install it.

I should note that if you’re doing this aftermarket, you’re going to want to purchase the Super Slider – and *not* the original Super Tube.  The reason is simple, the Super Slider adjusts so that you can make sure to hit your mounting points.

Here are some links to the tools and materials I used to get this done (and yes, these are our affiliate links):

  • RecPro RV Super Slider – If you’re installing in an EKKO in the same place we did, you can get by with the smallest model.
  • My Sliding Pad Creeper – I get under the RV way more than I should.  This thing makes it a snap.  AND BONUS!  It’s compact enough to travel with!
  • The Fein Multimaster – This was (as near as I can tell) the original of all the oscillating tools like this.  It comes in handy any time I need to make an odd-type cut.
  • ABS Cement – This stuff has been coming in handy a lot lately.  Especially since I started 3D printing things out of ABS!


Besides those items, there are always the usual shop supplies, nuts, bolts, etc.  But I never bother to list those out.  If you see something you’re interested in, let me know and I’ll add it to the list.

This project really did come together in just one evening after work.  So even if you don’t have my shop, it shouldn’t take you more than a day.

Let me know what you think.  Cheers!

      I did actually find a place to install a sewer storage tube on a Travato K. And I liked Lance and now your EKKO, but what I really want is your shop! And it’s so clean! BTW, another way to store a sewer hose safely is to lock the two ends together. Thanks for all the helpful tips!

      I have been looking at this video frame by frame to try to see what hitch installation the Ekko has. I would really appreciate it if you could tell me the make and model of the hitch as well as the towing capacity of the Ekko

        It’s a 5000 lb hitch. I believe it’s the Ford one, because there’s a 7 pin harness that works with the trailer brake controls in the dash.

      James, I would have hoped you would have used better safety goggles, or actually a full face shield when you used the hacksaw over your head to cut the metal while lying on the ground under the Ekko. I got a shaving of metal in my eye doing something similar 38 years ago. It was not a pleasant experience. I cringed when I saw what you were doing with just those small glasses on.

        I’m actually wearing two different pair in the video. Both pair are full-up prescription safety glasses. One pair is actually a goggle design, and the other has clear shields snapped into them. Thanks for your concern.

      Any suggestions on where we could do this on our Boldt 70BL? We’d love to have a Rhino hose but the under mount tube that came with Boldt is too short and not as wide. The hose that fits it is of less quality and tend to break down and leak.

      1. James - Post author

        I’m not familiar enough with the Boldt underbelly to make any recommendations. Sorry!
        BUT – if you get the Super Slider, it is of variable length, so it should be pretty easy to make it span between any two mounting points you can find.

        Our RV does not have rear bumper hose storage. There are blind spot monitor sensors in the rear bumper.
        Even if it did have storage in that bumper, it would not be big enough for most sewer accessories.

      Most of my hole saws cut metal just fine.

      So, I would have used a 6″ (or what ever) hole saw to cut the cutout by clamping a piece of thicker plywood to the trim to hold the centering screw bit of the hold saw (which would be some inches lower than the van). I don’t know if that makes sense.

      I think that would have made a neater cut.

      But, more important, I hate creeping under vehicles and sawing over my head.

        I get what you’re saying, and that might have worked. Didn’t occur to me to try it that way.
        But this trim was not exactly flat, so I don’t know if it would have worked.

      Ok this was not an official mod. Official mods require at least one trip to the store and one breakage of skin with blood and a burst of foul language. Having said that still a very nice project video.

      Hi James and Stefanie. Spot on, as usual. I was wondering what brand of “creeper” you got. There is a $25 one and. $75 “Magic Creeper”. Never saw something like that before. Looks very handy.

      1. Stefany

        Hi Charla! The one James got is linked in the post above, you can click the words and it goes exactly to the one he bought! ❤️

      Ok. Because!

      Regarding a drain hole… aren’t holes two way openings?
      Someone said water always finds a way to where you do not want it.

      That said… nice mod.

      1. James - Post author

        Yes, water could get in that hole.
        But the other end is not water tight, and it would eventually find its way out.
        (I drilled a hole in that forward end because once I glued it shut, it became water tight.)
