Load your trailer heavier in front (unless otherwise directed by the trailer manufacturer) The trailer should have about 60% of the cargo weight in front and 40% in the back. Secure your load to the trailer using rope and tie-downs.
The Superman Clone is one of the major villains of Superman: Doomsday.
He easily defeated the justice league before confronting Superman. Doomsday is the only one in main comics continuity to ever kill Superman; and he did so simply by beating the man of steel to death. Doomsday was killed in the battle, as well, but later healed himself and returned to life, stronger than before. Superman has encountered him on numerous occasions since.
