Travel trailer wine glass holder and flip up kitchen shelf

I thought about making a small table for my wine glass but was also thinking it would get knocked over easily. It doesn't budge when I get on or off of the couch. So I came up with this. I'll probably leave it where it is most of the time. I actually made the flip up counter extension about 8" wide the first time but removed it and this one is about 14". I find it very useful and don't see it getting in the way.
