Funny to read this. Why? Because our strap was getting in the way and I removed it. Well, one night I ended up on the dinette because guests took the master bed. At 2 a.m., I crashed to the floor and woke the whole trailer.
The table does not stay in place.
I planned to fabricate some sort of pin or something, but haven't figured it yet.
Oh, and it damaged the rails on mine some when it crashed down. On our last trailer, those same rails broke (I'm big), and I replaced them with 2x4's bolted in place...never fell again.
