As promised, here are the pics of my 'sewer solution'.

I used a clear 45 degree coupler to the dump connection and a Valterra screw type coupler to the outside connection. I used about a foot of hose to connect the two together.
To mount the outside Valterra connector, I cut a piece of Lexan to fit snuggly over the coupler and then screwed it to the existing hole opening as seen in the bottom pic.
No more having to feed the hose thru the opening, then attach the coupling. Very simple and easy to operate now. Total cost about $25.[/img]
