Load your first item on the trailer. Heavier items should be loaded first. Throw a blanket wrap around the item and secure it with rope.
Move the item to the desired spot on the trailer. This will be in the back of the trailer either in the left or right corner.
Look at the wall of the trailer and you will see boards on the walls with holes every few feet. This is where you will tie the tie-down straps or attach the bungee cord. Place the tie around the item and tie or attach to the wall board on each side of the item.
Place the next item in the next corner and cover. Use a tie strap or a bungee cord to secure this item.
Place the next item in between the two corner items. Cover the item and secure to the wallboard with a tie or bungee cord. Try to make the items fit together tightly instead of loose-fitting.
Continue placing items on the trailer and securing the wall items. The remaining middle items should fit snug so that there is no room for movement.
