I would filter through a 10 micron sock out of the truck through a pressurized filter setup (made from a 5 gallon bucket w/ a sealed top). From there, heat in an open drum with a standpipe and run through a 5 micron into a large storage tote (I have a couple 330 gal. totes if you need one). Then just do a final 5 micron while pumping into the truck.
