Had to tow a heavy load this morning. Ok did'nt fill the 1000ltr tank to full, about 400ltrs & had to go up hill, still done the job. What I have is a tank & Honda generator for my electric submers pump with 2inch hose to pump water from a river into the tank (fills tank full in 4&1/2mins). this job is normally done using a tractor with a full load. In the front I have a little 2 stroke pump with a 1 inch hose to pump the water out to water my greens.
