you are going to use a tip that gives you about 500 psi and 1/2 gal per min is not worth too much more money.
My question would you be able to run 2 wands of the bigger unit at 2 gal per min.
Would be nice to have a 6 gpm unit with 3000 psi and 2 wands.
The more the flow the faster you go.
If you had a way to carry a large amount of water and kept the system at your shop. Then used belt drive cold water units, then you would be where the car washer's are around here.
Big box truck,big tank,3 cold water belt drives.
They might even have 2 of the same rigs and one is filling as one is working because they never seem to stop or run out of water.
Not even a name on the truck.
