I have looked at all the Fairview documents for their regulators for RV's, and no where do I see any specs saying their units are only capable below 110 psi. We had a Fairview, which was the OE install, on our rig for many years, exposed to temperatures as low as 9 degrees and all the way up to over 115 degrees, and never had a problem. When it started leaking and the red/green indicator stopped working, a couple years ago, I did replace it with a Marshall MEGR-253H unit, and have had no issues with it. The Fairview may be less expensive than the Marshall regulators, but I really doubt they would or could be used if they weren't safe for RV service. We also had a slight whistle coming from the 30 psi red regulator a while back, but that went away after some time. I did purchase a new one in case it failed, but that one has remained in my spare parts tote ever since, as the red regulator is still working just fine.
