The standard removable pedestal legs are hopeless (just like "stabilizer" jacks, lol). We replaced our stock legs with Lance table legs. Very solid and look great. No holes in the floor to worry about either.
Did a mod on a previous TT and used an interlocking bracket mounted to the end of the table that attached to the wall along with a single folding leg. Worked well, but you want studs in the wall to screw the bracket to otherwise you may get some movement in the luan plywood. The bracket is a standard RV item.
