Hey Arne,
After seeing Kai's petcool installation at the Redwoods I've been considering adding that option to my tear. I don't camp often in campgrounds, but it would be nice to have the option if I want to.
Like you I'm considering running it up through the floor at the back of the galley and pipe it into the cabin. I'm still finishing off the galley so I have room to add the ducting. I'm thinking that rigid ducting under the trailer would be the way to go.
Kai used RV sewer fittings with bayonette mounts to attach the cooler to the trailer. It's 3 inch so it should work just fine.
