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.
