Surge protection is unnecessary unless you are plugged in and have a surge. Then it is tooooo late.

In thunderstorm country the lights may cut out for several seconds. A "recloser" has protected the line. But if the strike is between the transformer and your service there is no protection. I made my own protector. Two plates of copper separated with .005" mica spacers on the corners. The house is disconnected via a high current knife switch. One day I returned from a mini vacation and found no power. Lightning had hit somewhere on the 250' service drop. The grounded copper plates were gone. The 10 gauge wire from the plate to a ground rod was gone. The above ground part of the copper plated steel rod was mangled. The 3 wire service drop was melted and mangled. I had to buy lengths of 6 AWG copper wire, and a new "mufa" with meter base for the service drop. It was expensive.

I also dissected a power management RV service box that had been hit by lightning. The inside was charred and smelled horrible.

Your house is NOT subjected to power provided by all sorts of different campgrounds that may or may not have been wired by qualified people.

Look at a progressive EMS. I have had mine since 2014. It has saved issues on 3 separate times. 2 low power and 1 miss wired plug that I know of. The 2 low times the ems cut power before damage occurred and the missed wired plug was setup for 220 and once again would not pass power and nothing burned up including the trailer

A surge is not a foolproof device. But it does provide protection against surges.
Much like insurance you do not need it until disaster happens.
Do you have insurance on your house? Enough said

It all starts at a generating plant some goes to your house some to the campground. BTW my qualifications are a retired Master Electrician to post about surge protection and yours?

Yup, you need one.
But.... what you really need is an EMS for true protection.

As someone above said your real worry in a campground is a brownout. Much more likely to happen.

It's not necessary until lightning hits a tree about 15' from your camper.
Then you will give serious thought to installing one. Trust me.

Dang, that will make your hair stand on end... literally

Funny story, I had built my own subwoofer with 500amp hooked to 15" driver.

When I first set it up, watching a movie, and there was an on screen explosion, at the exact same time lightening hitting my next door neighbor's tree. I said holy cow, that sub really puts it out. Well it did, but not like that [emoticon]

Your basic trailer has just one thing that is worth more than $300 and that is the air conditioner. Air conditioners can be damaged by low voltage, so an inexpensive volt meter can tell you when it needs to be turned off. With an expensive EMS everything will be turned off if the voltage drops too low. One thing for sure is that there is a 100% chance that there will be $300 less in your wallet if you buy one and there is a very small chance that it will ever save you more than that.

I guess mine is not a "basic trailer". I have two AC units, a refrigerator, three TVs, satellite receivers and a microwave that are all quite costly to replace.

Most people have laptops, I pads, tablets or smart phones that they recharge, at some point in their trailer.

With that said, I have had some sort of RV for nearly 40 years and have never had a problem. I guess I am on borrowed time and I should think about getting a system to protect the electrical circuits.

What system are you recommending for a 50 amp RV?
