Lighting Storms, Ground?
Hi,
Florida! Lighting Storms!
Any recommendations on "Ground RV to earth".
So, I can live in peace in my Motorhome during Lighting Storms.
Thank you, all!
Fantastic Group!

If the RV isn't grounded (unplugged from the pedestal) the chances of being hit are very slim. Lighting pulls up a static bolt from the ground a few hundred feet and discharges into it. Tires are not a conductor condusive to that. Watch some high speed videos of strikes. It's why some people have all the hair on their back stand up before a strike. It was pulling electricity up through them. Thank God it picked another choice in the case of my friends.

While the RV is plugged to the pedestal, it has an earth ground through the ground wire to & thru the pedestal outlet. So you increase the risk of a lightning surge damaging your electrical system & appliances, but gain some ground protection.
I've lived in Florida for 45 years, more than 20 of them with our RVs sitting in the yard, plugged into power, and under trees. Have survived literally thousands of storms. There were a few times I thought the stick house suffered from a nearby strike, e.g. some piece of electronic gear failed to come back after an outage, but that was 20 years ago. I added a whole-house surge protector since then, plus electronics have generally improved their self-protection.
I'm not saying it can't happen, but am trying to add some perspective to the discussion.

No question, if an electrical storm threatens, disconnect shore power from shore outlet.
Nearby lightening strikes can follow shore wiring to your coach.

Yup.. Pull Da Plug. And I just enable the auto start on the gennie if the storm may last a few hours.

Lots of good advice above.
Driving an earth ground and connecting to the trailer is not likely to help with a lightning strike. It may cause problems with the system ground when connected to shore power.
The shore power pedestal provides earth ground. Disconnect shore power to reduce possibility of problems from a lightening strike on power grid wires. This of course disconnects the earth ground which is fine.

Unplugging from shore power only helps reduce damage to appliances, If you don't retract the steel jacks and receive, a strike being on tires doesn't help.

This. Stabilizers, leveling jacks and tongue jacks if in direct contact with the ground keep the chassis grounded

Yeah. You want them up or wood blocks under them.

If you got a direct hit with lightning, which travels thru the free air for thousands of feet, a few inchs of wood blocks isn't going to help.
