With multiple comments about high water pressure in some parks/campgrounds, I looked into various water pressure regulators. The Valterra with the PSI pressure gauge was my first choice but the reviews were not good.
I finally opted for a wall mounted Shurfo which eliminated the need to carry an extra item and connect/disconnect with every water connection.
This one: SHURFLO (183-029-18 ` White City Wall Mount Pressure Regulated Water from Amazon.com
Installation was really simply. Remove the 3 screws from the factory city water inlet, pull it out, unscrew the water line fitting, enlarge the opening in the camper wall to a 3.5" diameter (used a jig saw/very simple), screw the water line fitting onto the Shurflo, butyl caulk the 'wall side' of the Shurflo and push it into the wall and use it for a guide to drill the 4 screw pilot hole and run in 4 screws! Simple and quick and done!
