I have a set up that all I do is drive sprayer up to trailer, hook up hose and do chemicals from inside.  I plan on doing some changes/modifications in future but right now I end up sucking product from cone, through pump and into sprayer.  I have a jug slicer in the cone and my watre source for rinsing jugs is a 12 volt demand pump hooked up to a pressure tank.  I then can slice up jugs without having the main water pump running.  I then can rinse out about 4 or 5 jugs and have in the cone and ready to go.  Those jug slicers are nice!  I plan to redesign the system to not let chemicals go through pump.  I also plan to make a 250 gallon storage tank to have in the back ( I have a couple extra bulk tanks not used) that is hooked up with 2" inlet and outlets.  This tank will be used "mix" the dry products before sending out to sprayer. 

This project has been a work in progress for a couple years.
