I had previously mentioned
in another thread that I was looking for an alternative to storing my ill fitting Rhino sewer line with its oversized bayonet couplers in the 1950's bumper before I did irrevocable harm to it forcing it in and prying it out. I had wanted to add a PVC tube above the bumper but that would have obstructed the rear cargo door and that just wasn't going to happen. After much discussion here and a lot of YouTube videos later, I finally came up with a plan of action which I executed today.
If you're reading this, you're probably thinking, "

Not another set of pictures of a PVC fence post slung under the camper!".
Well ... yes. And no.
See, in all of those videos and on all those RV hack list sites, after the initial hanging of the post under the camper, I just never saw a closure system on a square setup like this that seemed as if it could have come from the factory that way. People used bungees, gate hooks, hex head screws (Really? Who keeps a nutdriver around for that kind of thing?) and I don't remember what all else.
I wanted my end caps to be easily secured AND look good doing it.
I started by cutting the post down to about 8 inches beyond the frame rails so that it wouldn't be a shin banging hazard. I should mention here that the 1950 has had an axle flip so I have plenty of ground clearance but it should still work at stock height. I picked up some metal brackets at Lowe's and screwed them in near the top of the post wall (after painting them with white Rustoleum) so that the hardware would not interfere with the hose and fittings as it went in and out.


Then I installed my secret weapon. Window sash locks and chain keepers.
I considered using vinyl coated wire for the keepers but they deteriorate in the sun over time and the vinyl cracks off so even if the chain rusts, it will still work for a long, long time.

Everything fits now, even the elbow although I sill have to detach it and it's a squeeze to get it in but I no longer have to wash it carefully and store it in a baggie inside the camper.

The chain is attached at one end to one of the screws that holds the bracket to the post and the other goes to a sheet metal screw that goes into a hole in the bottom of the post to lock the bottom of the cap into place. Then I pop the top of the cap into place and flip the sash lock closed.
Makes it look ten years younger, yeah?
I'm thinking about drilling some drain/evaporation holes but really, why? It's all plastic and there's nothing to rust from the moisture other than the stainless steel screwheads on the brackets. I'd rather keep the rain splashwater and the bugs out.
