From the preview, Dallas stacked his flour sacks near the lady to her right and Ken was farther away from her, but on the same side of the room. You can't see his stack. Ken's stack is in the extreme camera foreground on the left, underneath the camera lens. Similiar to the two boxes on the right. DanDrew's "box" is still empty. Their box is the empty one in front of Nick's.
I think DanDrew realize they are dead last at the roadblock and spend all their money on something, before going to the mat.
