Congrats on your new Lexi!
We'll have to have another rally sometime next spring so you can show it off.
As far as the sewer hose, I place all my sewer fittings and extra hose in a container which I store in the pass through storage. I also keep all my fresh water hoses and items in a seperate container. Works for me.
This picture shows the fresh water container. I usually stack it on top of the container that holds the sewer items.
