Keep in mind you do not have to spend 80 dollars to have a good pressure regulator just make sure it is not plastic they are not very good at all the brass regulators buy Marshal is about 15 to 20 dollars and work very well and you can get them with a gauge to monitor the water pressure, they have Ben around for years. Another thing to note is that the regulator is intended to protect the flexible water line going from the hose bib to your trailer and not necessarily the water lines in your trailer because the water lines in your trailer are the same water lines used in most new stick built homes in America today.
