Getting the sewer hose in is really easy, we've both done it. Use it, rinse it, shake it and run it up. He used a fence post cap, put holes through the post and the cap. You run a long bolt through to hold the hose in. When you want to use it, pull the bolt and the hose falls out.
It requires holding the hose up a little on one side to get the bolt through. It's easy once you do it.
I think it would be OK with the bolt holding the hose in and no cap but my husband thinks the cap looks better.
I do not tolerate much jiggering with stuff. My husband has the patience of a saint and does not mind complicated adjustments and I just can't. You wouldn't believe how he was tying his kayak to his truck, I thought I would lose my mind just watching and I could never learn those complicated knots. Well, I helped him out,
got some ratchets and straps. Takes a few minutes now for both of them.
I saw this sewer setup on an older truck camper, and took a lot of pictures. The truck camper looked like it came with this, so Don had to figure out how to attach ours. He used plumbing tape with rubber strips underneath the tape and attached to the ladder. I was afraid it would be really tacky, but it's not bad. I can't tolerate tacky either. This MH has brought out my inner doll house owner.
