I have a new EB as well (25') and I can attest that this is an extreme problem and unfortunately Airstream was not much help. They asked: "didn't you test the table before you purchased the trailer?" To which I responded: "Well, the dealership wasn't too keen on me and the family sitting down to eat a meal before we purchased!" I cannot fathom that it is acceptable to purchase a trailer of this price point and have a table that we can't have a meal in without risk of tipping drinks.
The weak link isn't where the legs mount in to the floor, it is the plastic female receivers mounted under the table top.
I have seen the other thread, and was confused at the best replacement legs as I don't want to re-drill the floor.
