We have an A liner Expedition (and previously a Classic). We love it, except for the dinette table which is always wobbly. I’ve tried twisting it firmly into the base, I’ve tried pushing/pounding it down hard, etc. When I do get it Fairly firm it is hard to pull it out when we take down. This last time it was firmly in place, then I twisted the top to release it, and pulled the table top off the metal ring attached to the table, liberating the six screws. Grrr. I’m redrilling new holes, reattaching it. But how do you get the table to quit wiggling when you place the metal post into the ring on the floor?? Thanks. Happy Fourth of July.
