Our Cardinal came already equipped with adjustable tie-downs for each recliner, plus the dinette chairs. Keeps everything from rocking around, or scooting across the floor while towing. Easy to install if you haven't got them already, so long as you have a nice wood floor to secure the ends of the straps.
Those "tie downs" anchored for dinette by FR are pretty darn strong. My dining chairs do not "budge" when secured. IF A DO IT YOURSELF PROJECT, make darn sure you do not do more to damage your floors vs securing chairs. Recliners are simply turned back to back and adjustable banded together. No screws or hardware required. Been 1/2 way xcross US and they did not move one inch. Having said that, there IS CARPET floor covering in this area on my unit.
