It amazes me how people worry about "what ifs".
Personally in 30,000 mile of towing across a couple of dozen states, I have never had water pressure that my little brass regulator or power issues that my 2000 joule surge protector/polarity checker has not handled.
I have had terrible tasting or no water, I have had power failures but spigot wars? Let's get real.
I am sure there are those who have had these issues, And yes I have had a few major annoyances, the most exciting being a road hazard that shredded my tire, bent the rim and broke one of the TT springs on the Interstate.
But it is all part of the RV life.
