When we bought our 5th wheel (used) the table was 'not' screwed or secured to the floor and the two swivel rockers, at the rear, had no way of securing them either.
I now have securing points for the table and the two swivel rockers.
We will often slide the table to a different position to view the TV while eating then slide it back into it's normal position when finished.
I placed the secure points / tie down anchors so the belt pulls the 2 dining chairs into the table and holds it all in place under way.(we only travel with 2 dining chairs)
Note: I use 'pool noodles' cut to fit to provide 'anti-chafe' spacers where the chairs and table touch...and then snug down the tie down belt.
If you need more info on what I used for anchors...let me know.
