The cost of transporting goods over long distances with a trailer is greatly reduced by the mechanical law of motion which states that it is possible for a tow vehicle(Even human/animal) to pull a load on rolling wheels which is more than 2-3 times its own weight/Volume. A 1 ton pick up can therefore easily pull 3tons of cargo.
