For us... The Park rules said I had to have rigged material sewer hose (pipe). We spoke with management, asking them what I should do, we together worked out my problem (not their problem). Turns out the rule was put in place because certain times of the year birds would peck at the sewer hose. The RV style hose the birds could get thru after pecking at it for some time. If we left and the lot was vacant, I then understood why the park had such a rule. Working with park management the end result was to make sewer pipe "bird proof". I had a "plug" fitting that fit into the end of sewer hose, so hose was "air tight". My flexible (rv style) sewer pipe had have a rain gutter under it and elevated and then put rain gutter on top. I used "zip" ties to keep them in place. That pleased us and the park. As far as backing up next to the hose so connections are in same spot. I have a tire chock block that I don't move. When we come back made it much easier to back up in same exact spot.
Hope this helps.
