Explanation:

Answer 2

I am pretty sure that the the best method to use when loading a trailer to have it "make weight" is to make it heavier in the nose and tail by attaching additional heavy things. You have to balance the weight and if you add some on these two points it will be steady and equable.
Hope you will find it helpful.
