DIY RV Sewer Hose Storage

If you are looking for a convenient, low cost way to store your sewer hose, this DIY RV sewer hose storage solution is my favorite. With this solution you don’t have to worry about losing one of those rubber bumper caps, or reaching up in that nasty bumper or storage tube to get your hose out anymore.

The sewer hose is stored conveniently below your RV on a tray that slides out to access you hose and adapters. Located near the dump valves and sewer outlet. The basic design consists of vinyl fence post, caps, hinges, a latch and a vinyl rain gutter. Because everything is made of vinyl it will last a long time, will never rust and can be easily hosed off when needed.

Required Materials

  • 5” x 5” x 8’ vinyl fence post, 1 piece
  • 5” x 5” vinyl post cap, 2 pieces
  • 4.5” half round vinyl rain gutter 10’ long, 1 piece
  • 4.5” half round vinyl rain gutter end cap, 3 pieces
  • 1” x 1” zinc plated door hinge, 2 pieces
  • Zinc plated draw latch (about 2.5” long), 1 piece
  • 1.25” wide foam rubber weatherstrip, 1pack
  • 1-3/8” x 0.075” thick x 6’ plated steel slotted metal bar, 1 piece
  • #8 x 0.75” Zinc-Plated Self-Drilling Interior/Exterior Sheet Metal Screws, 4 pieces


  • Look under your RV and pick a location to mount the fence post. Make sure there are frame rails to attach the straps at each end.  Also make sure there isn’t anything sticking down where you plan to mount the post.
  • Measure the width under your RV where you plan to mount post, remember you do not have to go all the way across as long as you have mounting locations near each end. Cut the fence post to the width measured.
  • Slide a post cap on to one end of the post. Drill 2 holes for a rivet on opposite sides of the cap and install the rivets.
  • On the opposite end of the post decide which way you would like to door to swing, then install the second cap sliding it a little less than ½ way on to the post. This will allow it to swing open.
  • Slide the 2 hinges between the cap and post. Mark the hole locations on the post with a pencil.
  • Remove the hinges and cap and drill holes for the rivets where your marks are.
  • Install both hinges with rivets.
  • Now slide the cap back on over the hinges and test the opening and closing on the door. If the door gets stuck slide it out a little further so it swings open easily.  Once you determine the proper location mark the holes, drill and attach the door with rivets.
  • On the side opposite from the hinges line up the draw latch on the center of the post and attach it with rivets.
  • Attach a cap to one end of the rain gutter using 3 rivets. 1 on the each side at the top and 1 at the bottom make sure to insert the rivets so the smooth head in on the outside of the gutter.
  • Slide the gutter into the post until it hits the fixed end cap and make a mark about ½” inch inside the post. Remove the gutter and cut it at the mark.
  • Install a cap at the open end of the gutter and then 1 more in far enough to hold your hose adapter and anything else you would like to prevent from sliding around. Just make sure to leave enough room in the long section for your hose.
  • Cut the metal strip into 2 pieces about 20” long
  • Center the strip on the bottom of the tube and mark the sides of the post. Using 2 pairs of pliers or a vice bend the metal into the shape of a squared off U.  Make the U slightly wider than the post so you can get the weather stripping between the post and the bracket.
  • Place the U over the post and mark the top to create the “ear”
  • Bed the ears so that they are slightly below the top of the post this way the post will be squeezed tight against the frame of the RV.
  • Cut the weatherstrip to fit the inside of the brackets and stick it on each of them.
  • Measure the distance from the end of where the post will be to your mounting locations, then slide the brackets over the post at those positions.
  • Get someone to help you hold the post under the RV and transfer the hole locations in the bracket to the frame
  • After all the hole locations are marked attach the post with the self tapping screws.

That’s it your DIY RV Sewer Hose Storage is complete!


  • I had access to some stainless steel sheet metal that I used for the brackets, but if you do not the slotted metal bar in the materials list should be available at any big box hardware store and will be easier to work with.
  • If you would like to add drainage drill a ½” hole somewhere in bottom of the post to allow water to drain out more easily.
