I had heard of the wobble. It concerns me because one of the things we want is to be able to use the table for kitchen prep work when we're forced to cook inside. Doesn't matter how big your kitchen is, you can always use more counter space. And, of course, trying to work on a wobbly counter is quite irritating.
Help me understand the existing table... As I understand it, there is a base table supported on a couple of tubular legs, and the true table surface sits on top of this with a sliding mechanism between.
Is there any reason that the bottom of the slide mechanism couldn't be fixed to the trailer wall? If that were done, the wobble should be pretty much eliminated.
In looking for pictures of the 19' dinette I ran across this thread on fiberglassrv: More Escape 19 mod pictures (some one asked) - Fiberglass RV
That looks like an excellent modification (except for the fact that it eliminates any possibility of doing a better job of eliminating the wobble...)
