In a case like this usually there won't be enough weight on the fifth wheel for good traction so the dolly will be hooked to the trailer and then to a tractor fitted with a weight box on the fifth wheel and loaded down for as much traction as possible. Also depending on load size and weight restrictions you will need a certain number of axles/wheels and tires to distribute the load out.
