witnesses are about. Make your final approach run at normal speeds and brake normally.... If possible, dump the trash while remaining inside the bed of the pickup.
If necessary, one person can hop out and dump the boxes that the other hands to him or her. Usually we leave the boxes at the scene, since they’re clean of fingerprints, anyway. We rarely get them from the same dumpster twice, further impeding any attempts to trace us. Besides, the poor slob who gets his trash back will need something to put it in!
