Surge protector
I know the best kind are the ones which would be wired into the system, but saw this today and wondered if it would be any good. Is this a "better than nothing" or "you get what you pay for" situation...

Whether a simple surge protector or "high dollar" EMS any surge exceeding the rating of the unit will destroy the MOVs (Metal Oxide Varistors) used to direct excessive current flow to ground.

That is not what a Progressive does. Word 'surge' has numerous unrelated meanings. Some call reverse polarity a surge. Some call an undervoltage a surge. The Progressive disconnects power when some types of anomalies (surges) exist. MOVs are irrelevant to those anomalies.
Well here we go again, yet another of your over complicated technical replies that almost no one else will understand, or in fact even care to understand. :R The point of this discussion is that there are significant differences between so-called "simple surge protectors" and more costly EMS units that not only include surge protection but offer features designed to protect an RV from the many vagaries encountered with park power systems. How an EMS does this is of little concern to the vast majority, the only important issue being that it DOES. :B
