Water Pressure

[RKassl]

I am building an external in-line water filer for the Monty. We are going to be camping at a CG that a lot of pressure in there fresh water hook up, I am going to use a pressure limiter but also wanted to put a pressure gauge also in-line to make sure no damage to the system. What is a desirable fresh water pressure for the Montana, and what is considered "too high"

Thanks
