They say saving 4,000 gallons of diesel per year per truck. That's pretty good. They also mention it's a heavy system, probably another reason you don't see it on a 2 ton step van (payload) but you might on a 20 ton garbage truck.

I would bet that almost every hydraulic component in those trucks is standard industrial hydraulics. Industrial hydraulics are designed to run 24/7 for 30 years with only an occasional filter change. Size and weight are not a priority.

A hydraulic system designed for commercial vehicle use would have, say, a 20 year design life running 2000 hours per year. Size and weight would be a priority. It would be an entirely different system.
