I'm kinda scattered over 120 miles, 2- 300 loads a year.  Have a 10 wheeler w 2 1500 tanks in the yard, then have a 10 wheeler set up with a 2800 gallon tank of CLEAN WATER , 2" pump, inductor, 8' of cage for chemicals on front that I have someone in most of the time when I'm spraying so the sprayer pulls up to the end & loads.  I also have a pintle hitch combine trailer I haul the sprayer where needed also.

Thing I like about this is the quart/2 that spills when  the tank is full is not a concern when it's in 2-300 different spots, not all in 1 place.
