Myself I would look into the belt drive cold water systems. The direst drive units are good but they seem to have a short life expecially decause people use them at 120% capacity. Gpm is key and the size of the pump is directly related to longevity. If you went with the 5.5 GPM it will make your operation way more flexable. Or run the 5.5 with a 4.0GPM each on thier own unloader and return line and T them together on the outlet side of the unloader with quick connects. Use the 5.5 for rinsing and the 4.0 for chem application and/or heat. put them together for some good cleaning fun!!

If you are trying to get the 8GPM you want I would stay with the 200Gal reserve tank at a min. This will give you 25 min of wash time with no hook up. With a hook up you might get 35-40 before you got low in the water department.

Good luck and shop frugally. What is the going rate for a 10.5 GPM skid mounted unit vs a three piece unit running all the pieces individually.
