First lightning forecast

Absolutely unhook from shore power if lightening is imminent.

Surge protectors can give you a FALSE sense of security. But, none of them are designed to control a nearby lightening strike.

When parked at campsite. Do you unhook from shore power? Jacks up or down? And are they on some kind of pad, plastic, wood?

I unplug from shore power and start the inverter so we can watch TV and use the laptop to see where the cells are and which direction they are moving. Weather Underground has some neat maps showing that.

I have a friend with the same year and model motor home I have. In 2005 his was hit by lightning. It didn't hurt him or his wife but he had to take it to the factory to get it repaired. The roof was replaced and there was a lot of collateral damage to the electronics.
The cost to the insurance company was over $20,000 as I recall.

an old article but some good info. If in a campground, we unplug from shore power. I unplug my computer although I have a surge protector. We do not drive in thunderstorms with lightening, heavy rain or wind. I check the weather for the next 5 days before we leave and if there are storms we wait them out, or arrive early before afternoon storms hit. If by chance we do get caught driving, we pull into a truck stop, parking lot or rest area.

I don't worry about lightning but do watch for wind. Our house got hit by lightning once and on Pentecost Sunday in 1989 I was playing the organ at Church when we got hit by Lightning. Organ and chimes were out for the next year until they got redone. That was a pipe organ that got hit. Funnty thing was the zymbelstern started playing by itself. If I can't stop it at home or Church why worry about it. It does put on a great show and we have nice front windows to watch it from. Staying inside the MH is probably the safest because of the Faraday Cage you are in. A metal frame will normally spread the strike to the ground.

We generally pull into a rest area . . . fire up the genny and have a cup of coffee and wait for the storm to pass or slow down.

We do not full time, but whenever we pull into a park for the night, if it is lightening my husband hooks up our electric and cable so we can keep an eye out on the weather. If the lightening is in our area, we just pull into our spot and wait for the lightening to quit. Heard of too many people being killed from lightening.

If we are on the road, I pull off the highway and try to park at a truck stop or rest area near the truckers. Just recently we had weather change on us while we were on the road. I got hit from the side with a gust of wind. When I saw the 18 wheelers pulling off at the next exit, I figured it was a good idea for me too. I looked at the weather channel on my smart phone while sitting in a parking lot (just got it and was learning how to use it) we found we were under thunderstorm watch and heavy gusting winds. When my husband went into the truck stop to get us some snacks, they invited us to go around to the back to park with the trucks. Where I was, I could watch when the truckers were leaving, so we stayed in the front parking lot.

I have seen too many accidents on the news of buses, RVs and 18 wheelers who were pushed over because of gusting winds or fast moving water. Better safe than sorry. Even a flooding underpass can move an RV or 18 wheeler.
