| I've done them various ways but all involve steel. I'd use either a 4x10" I beam or 3x8x1/4" channel for the sills. I then put crossmembers on at 2' spacing using either 2x2x1/8" HSS or 1-1/4x3" channel. I then run 2-3" angle along the sides to join the crossmembers. I also box the ends of the sills in with a heavy cross front and back between the sills.
Then you deck it with 2" rough lumber of your choice.
These wagons with oak sills laminated together and 4x6" cross members.... probably weight nearly twice as much as mine. Neighbours have some like that... and I've towed them. They're a load empty... and they won't last as long.
