Thanks for the come back.
I didn't know about the irv2 site, but have been binge reading. However, my bride needs me to plant the spring time pretties, so I gotta go for now.
I was disappointed in ORV using Lippert for some components. It's sort of like anything with the name "Daniels" could lead to problems--you know, Charlie Daniels, Jack Daniels, Stormy Daniels---. I'm kidding!
There was one fella that did an easy mod to the kitchen drain so it would go into the main drain. I've had two rigs with the same factory setup and they have worked fine.
The search continues. Thanks again...
