Now: You have a slight understanding problem I suspect.. The Camco HIGH FLOW regulator (The one with wings) is not all that much different in pressure, 45-55 pounds is the standard for all regulators used with RV.. What makes the difference is not higher pressure, it is larger openings internally allowing MORE water to flow without increasing the pressure.
A Watts of at least 1/2 inch will have still larger openings, as does the Valterra adjustable. A Sur-Flow has about the same capacity as the one you are using now.
In support of this statement, I use a standard house Watts regulator set at 60PSI. Gives me great flow or volume for showers. One person who claims to have tested some of these regulators states that the standard Camco RV gives 2 - 3 GPM while the Watts standard house gives 6-9 GPM. Big difference! At the time he was testing there was no RV High flow, so don't know how that might compare.
