Sewer hose and Valterra Tube

My take on a solution I saw someone else do. I like having the slinkey right by the dump valves.

I bolted to the vertical bars with 1/4-20 stainless bolts. 5" hole saw and auto trim dresses out the hole. I used an extra Valterra slip mount and had to shorten the tube for the brackets to line up with the bars. The tub should be mounted to the rack before setting the rack back on the trailer frame for the final bolt-up. 
This is how one takes a two minute job and turns it into an all day project.

I recently completed adding a Valterra 64" sewer hose tube

to my 2019 320 S Boondock Lite.  I did not do anything new or unique than others on this forum have done, but I am posting some photos for whatever assistance they may provide to others considering this modification.

At the suggestion of @SteveW (thank you!), I made the aluminum cutouts using  a jigsaw and light metal blade:

Also at the suggestion of @SteveW , I created a cardboard template, which was simply a tracing of the outer diameter of the end of the Valterra tube.  It worked out to an approximate 5" diameter circle.  As you can see in the photo below, the Boondock platform raised the aluminum tub above the A-Frame, so I "eyed it" to determine approximately how high up on the aluminum tub to place the cardboard pattern for cutting.

To determine where to place the template, I measured in approximately 3/4" or so from the edge of the Boondock platform to the outer edge of the template on both sides of the tub so that the cuts would be in the same general location.  [Another option would be to measure the distance from the aluminum diamond plate on the trailer body as a common point of reference to equalize the cuts (i.e., measure equal distances from the lowest/narrow point of the edge of the tub that butts up against the trailer body - - if you do that, you will need to slightly peel back the rubber trim at that location so you can measure from the metal point at the bottom of the tub to the Boondock platform on both sides of the tub).]

The placement of the height of the cut later allowed me to lift the Valterra tube up from where it would otherwise rest on the A-frame to a position that lines up better with the Boondock platform.  Also, I made the cuts fairly close to the Boondock platform to provide sufficient clearance between the Valterra tube and the propane lines that are secured to the diamond plate on the camper body.





I removed the aluminum tub from the trailer to make the cuts, which were fairly easy to complete with the jigsaw and recommended blade.  My wife helped hold/brace the aluminum tub while I made the cuts.  Be aware that when you cut the aluminum, a lot of small aluminum particles/shavings will be thrown off during the cutting process.  Therefore, you may want to do the cutting outside so those particles do not get all over your garage floor, or place some sort of covering on the floor to catch the particles.  If all else fails, you can do as I did and vacuum up the aluminum particles.

After making the cuts to the tub, I lined the rough/sharp edges with 1/8" automotive edge trim:

I used a pair of tin snips to cut the trim to size, because there are metal tabs lining the inside edge of the trim to hold it securely in place against the aluminum cuts.





I had originally planned on cutting inside the cut lines that I had traced, simply because the diameter of the body of the tube is less than 5" in diameter.  However, I forgot to do that and instead cut along the line I had traced with a permanent marker.  But, it probably worked out for the best.  When I was ready to position the tube inside the cuts, I first laid the tube on the camper A-frame and then set the tub back on the frame.  Next, I bent/pulled the pliable aluminum of the tub outward slightly toward the tongue of the camper to get the tube to pop into the cuts.  It made for a pretty clean fit (with room for some movement, if needed), plus the tube has no way of slipping out from behind the tub, even without anything securing it to the camper.)

Here are the cutouts:



Below is a view of what the Valterra tube looked like while resting on the A-frame of the camper before I secured it to the Boondock platform.



Using a similar method of attachment as that used by @hymie , I passed two zip-ties through openings in the plastic mounting legs of the Valterra tube.  This allowed me to pull the tube upward and align it tightly against the base of the platform.  I did not have thicker/wider zip-ties immediately available, so I used some thinner high/low temp (and UV resistant) ties to secure the tube to the platform uprights.  I think they will hold well, since there is little weight/force on them, but I still plan on replacing them with wider and thicker zip-ties.







As an aside, as others have already noted, my 15' Rhino Flex sewer hose and attachments fit easily inside the Valterra tube.  The only thing I had to do was remove the 4 in 1 universal adapter from the clear elbow and turn it slightly at an angle to get it to slide into the storage tube.

My thanks to others who have previously posted similar modifications.  It made my shot at it much easier.  (Greg)
