So far this year while camp hosting in Okotoks, AB, we have had a number of very active thunderstorms rolling through the area. I have been unplugging us as a means of protecting our trailer and it's electrical systems. We have personal experience as to what a nearby lightning strike can do as we had a strike about a year before selling our house in Kamloops. Even though that strike only hit a tree in our back yard, the surge took out over $3,000 worth of electronics in our house and caused damage to others up and down our block.

easy to access here when plugging in.
