Re: sewer hose?
Jim, I see what you mean. I still have the original holder that came with the Escape and found that the sanded down RhinoFlex would not pass through the female adapter.
I replace the entire holder since the RhinoFlex is longer than what Escape furnished. I did try, at first, to extend the original holder by cutting the end cap and adding a piece of foot long pipe using a coupler. However, the RhinoFlex right angle connector would not go pass the new joint. So I made a complete new holder. I got the 4" pipe from a local hardware store that offer cut-to-length pricing. I got the female adapter and end cap at Lowe's. I kept and used the original screw-in cap as well as the one nut and bolt that attached the holder to the frame (on the driver's side). After sanding the RhinoFlex ribs and the female adapter lip, the RhinoFlex hose, including the right angle connector, goes in nicely.
Since we are both going to the Merritt Rally, you could see what my holder looks like. Or if you want to take a chance I could get a female adapter for you or I might even be persuaded to makeup a complete holder.
I did explore using the 5" square fence post. But I didn't do it because:
1) Lowe's and Home Depot had two selections, one was too short and the longer one too expensive.
2) Both the box stores and a local fence company's 5" post were heavy, way heavy
3) The space between the trailer and the spare tire looked like the 5" post would be a very tight fit, if at all (unless you go under the frame).
4) I didn't care for the end caps and how they attached to the 5" post
