Heck...

Even 2x2's would be enough. You just put the 'stiffener' joints in the middle of each sheet of ply.

When I made my game table (BattleTech) I used 2x4's, and placed heavy door hinges at the corners so I could easily dis-assemble the beast. Thats another option, square-frame each 'section', wait until ya get to the meet, then mount the hinges to 'mate' the stiffened sections.

And I agree, a full trestle invites too much movement if bumped, and trucks going 'Off the Edge of the Earth' so to speak. But just an underframe would definately eliminate that warpage.

Sealing the boards might help too, as I'd bet that was caused by the moisture of the grass/ground under them, and the heat/sunlight above.

Just some idle observations,
