Denny, I suspect you're not getting much response because this is a fairly rare layout. The large majority of forum members with 16' and larger trailers have bathroom versions.
If you do a Google site search on "Scamp layout 3" (blue bar under your log-in info, "search," down to "site search/Google") a few old classified ads turn up. Here's one: SOLD 1981 16' Scamp - Layout 3 - Loads New! $7500
. These were the only pictures that showed the table. To my eye it looks too high for dining from the sofa. Perhaps Scamp
could lower it, or leave it unattached for you to install. Lowering it would involve cutting down the folding table leg.
Here is a reno thread from someone who apparently thinks like you do. They removed the bathroom from a layout 4 and built a table very similar to the one Scamp includes on layout 3: Inside renovations complete!
. It does appear to be mounted lower than the factory set-up. They have been on the forum as recently as August, so you might send them a private message asking how the table works as a dinette.
I also wonder if something like this might work with a small folding cafe table in the corner (that could be moved outside when the weather is nice). The little window tells me this was also done by someone that removed the side bathroom.
