What difference hauling water vs not hauling. water being a small percentage of GCVW, and no significant change in fuel use.
With water and with my off road car that weighs about 2100lbs in the garage area of the toy hauler. It puts my GCVW at its maximum. So it does matter, I. average about 1mpg better without water, and lower temps on my dually when running through mountain passes which most of this trip is... the last time I weighed fully loaded to make sure I was still legal wa 24,500 total.
If the trip was flat ground... the difference is negligible.
