We have a new 2014 832ISBS, and the table is screwed solid into the floor. The four chairs are free to move about, of course, but surprisingly, they don't budge during towing, even on crummy roads (and we have several miles of rutted gravel before we hit a back-county, hard-surface road). There are tie down straps to secure the chairs to the table's pedestal, but dealer didn't recommend doing so, and darn if they weren't right. The slide clearance is close on the two Lazy-boy recliners, but they don't seem to budge either.
