I have a V8, gas powers ,step van
I would like to add a soft serve ice cream machine to my truck with out a generator .
So I would like to get informed before not to go to see my mechanic.
Or if any body can put all the system together ?
I would pay for this.

I know that david cummins trucks (the soft ice cream freezer is driven by a power take off from the vehicle engine )
How you wire it and put together ?
Exactly what extra parts I need ?

What kind soft serve machine it should be ( what watt ,what volt etc )

And also any disadvantage of david cummins trucks ?especially used ones?

Thank lots in advance
