When to use water pressure regulator on fiver?

Recently we were at a campground that had 40psi for water coming into our fiver. Normally we've seen 50+ or 60+. The question I have is if water pressure is low I am guessing you do not need a regul...

Maybe someone can enlighten me on this. All the newer RV's are being built using PEX tubing for water lines (same as in the new houses)which are rated for 160 psi. Even the older polyethylene tubing used years ago was good for at least 100 psi. I have yet to run across a water system higher than 70 psi. So why do people insist on using a PRV?
