I own a 07 29bhs, We had the same problem. The table would move and squeak when walking around. I had a old foldable chair and cut one of the legs to length and hammered the two ends flat and used the screws in the window frame and under the table. It works great, you can put your elbows on the table and doesn't move. We don't use the table for sleeping, but if we ever needed to it wouldn't be that hard to take it apart. I keep a small electric screwdriver in camper.
