I would urge to "ALWAYS USE A REGULATOR" even if the campground supply seems to be OK when you set up camp. I've been to countless campgrounds where during the day, the pressure is 40-60 PSI, and at night, when the surrounding sub-divisions and the other trailers in the campground aren't using water, the pressure will increase dramatically. As an example, the Tourist Park Campground in Marquette Michigan has water pressure, during the day, that ranges around 50-70PSI. At night, when the city transportation maintenance facility (next to the campground) closes, the water pressure will rise, sometimes as high as 160 PSI. That's enough to destroy almost any RV water plumbing system.

And, the problem is that it only "creeps up to critical pressure" after you check it and think "everything is great".....
