First would be a good design that was rigid. Like, it moves out and gets bolted in place, not just hanging out there.
Second would be a good flexible seal... This could actually be a seal just pushed in place when the slide out was extended. Like a piece of that foam pipe insulation shoved into the gap.
Third,and most important, would be an open bottom on the interior frame that would allow water that got past the seal to have a way out the bottom.
Personally, I would only bother if I was going to a foot well and table design, and wanted another 12-18" of room near the table..... Could be a neat picture window thing.... would lose one door, though....
I would add some things from talking with several RV experts:
Ensure a good fit, most leaks are caused by excessive or abnormal gaps. Make sure the opening and the slide itself are perfectly aligned.
Add support around the openings and any longer surfaces, things tend to sag over time and they leak at the sags.
Ensure sufficient but not excessive clearance for the seals, a rolled under seal leaks.
Ensure it moves straight in and out and does not bind, a twisted slide damages the sealsgoinf in and out.
More as I remember...
