Thanks for the lightning info Mustang65. Even though we might be able to comply totally, we can reduce the chances. Can anyone explain the energy flow from negative to positive, negative cloud bottom to neutral tree tops. Is that the only direction of flow? Are RV's of positive variety only? Can we change the polarity?

Wouldn't the tree top be a positive charge seeing that it is connected to the earth via the trunk and root system? Buildings would also be positive polarity as well.

I am not going to worry about it.

Not my trailer, but in 2004 about a week after we got the power back on following Hurricane Charley, lightning zapped a sand pine in our neighbor's yard..............and found it's way into our home's electrical system via the ground stake at the meter can. Fried several plug in surge suppressors, the meter base surge suppressor, 2 smoke detectors, a cordless phone base, a new TV and home theater. After the storm passed I went outside in my "what the hell was that?" mode looking for what/who got hit. Saw the pine tree with scorched bark about 15' up from the base of the trunk, but no other indication of a lightning strike.................until the tree died about 2 years later.

Don't know about polarity, but that stuff packs a wallop even with an indirect hit.................and that was the second time in the 27 years in our current home we've gotten an indirect jolt.

Me either but I like to discuss lightning and its unusual behaviors.
