I like the idea of the PTO drive units. This was the way I was heading untill I thought about fuel. At close to five dollars a gallon around here this is an issue. For at most these pumps / generators will use 80-90HP while the engine (truck) will develope close to 200HP @1500RPM. Seems to be a bit of a waste of fuel and engine wear and tear.

While washing our trucks are normally turned off and the pump engine is on. Sure I might burn out a starter every year or so but they are cheaper to replace than letting the truck run.

Just some food for thought.
