3) Dinette bench top lids. One of the things we noticed was the hatch covers on the dinettes ‘bend’ under weight and can suddenly collapse into the bench, esp. in warmer weather and def when kneeled upon! Solution was to use a 3/8” thick sheet of abs plastic connected as a hinged lid to the benches, an unanticipated bonus was that it also perfectly leveled the platform when the table was folded down into a bed!
