Paul - I was thinking along the same lines, but was afraid to suggest. The design with 2 pedestals is inherently bad. Table needs 4 points of support. Folding table, even not rock-solid, might be better than the current one. But... 2 folding legs on the "entry" end of the table necessitates (gasp) removal of the benches and use of chairs instead.
You can get a pair of folding chairs. Table attached to the wall and resting on 2 legs. Saw this on one photo of trailer for sale. Some people converted their motorhomes this way, here, on this forum. With normal dining chairs. Missing storage was TAD compensated by adding very nice shelf/bookcase above the wheel well, under the table (this space was wasted). Search the forum.
