Careful. If this is on the Challenger the Anderson water center can handle a max pressure of 100 psi. The owner's manual, however, states that anything over 55 PSI should be considered "excessive" and lead to damage within the fresh water system.
I use a 50 PSI regulator when connecting to campground water systems.
