Ours came, with an Aqua Flow, I think. They changed it out for one of the others after they wrecked it. it was very quiet. I don't have the books here of i could give you a model number if they still make them. All I see on the net is pool pumps. Some of or maybe all the Prevost conversions use a 100 volt jet pack water pump. Somewhat similar to what some homeowners use on some wells.
Depending on power demands wiring to the Inverter and using one of them would be great. Cost,I'm guessing would be three hundred dollars or so and wiring.
I don't remember the brand.
