Moving Change Up fields between buildings

I have a need to move 4 complete Change Up fields from one building to another in a 8’ x 12’ trailer.

The field walls are set up Kloberg style with thumb nuts so I can quickly get the center of each wall off of the corners. I would leave the goals attached to the walls.

I would take each corner and stand it up in the trailer, one face would be flat on the floor, the other face would be on the wall (and I’d strap it to the wall to keep it from folding up.

I’d then put the center sections down the middle nestling the still attached goals.

Center goals would just get stacked in the leftover space.

Is there a better way to do this?
