I carry two sewer hoses and now a sewer solution.
The smaller sewer hose is in the tubular container that Scamp
mounts on the front of the trailer that Byron has pictured.
Secondarily we carry a longer hose in a almost 5" x 5" x 4' fence post that is screwed to our rear bumper. I have drilled holes in the bottom of my fence post to let it drain.
Thirdly we recently purchased a Sewer Solution. We use it to pump out our gray and black tanks into the clothes washer's drain in our son's cellar while parked in his driveway. It allows us to use a water hose to pump about 50'. It's very handy when parked at home or when visiting the kids. We do not normally carry this item.
(This is our second Sewer Solution. We gave our first one to our Maine son to to pump his Casita
16 out again using a long 3/4 inch garden hose.)
We keep the Sewer Solution in one of our 5 plastic boxs attached to the bottom of our Scamp
One nice attribute of the Sewer Solution, particularly with the Scamp with its separate tank drains is the SS ability to send a high speed jet of water directly into the respective tanks and clean the tanks pretty well. This same Jet can be re-directed to clean the SS drain hose.
I have plastic post caps on each end of the Fence post. They fit pretty tightly. In addition I drilled a hole thru the caps and the posts and use a #8 wing nut simply screwed thru the cap into the post.
Additionally I run a piece of bungee cord thru the center of the cap and into a hole thru the post with a knot on each end.
There's probably pictures under Modifications/Preparing a 1991 Scamp. If you can't find them let me know and I'll repost.
The attached picture is of my son's trailer. He does not use them for a sewer hose. One is used for his clothes line poles. The other is presently empty. Their primary purpose is to support a bumper box.
One advantage of the 5"x5" fence post is that it is large enough to hold hose hardware and things like a rubber donut, ....
