Just had a look at dielectric strength of air. Consensus of the pages that I've looked at so far is 3,000,000 V/M. If we go with the voltage number presented above then your tires will need to be about 84 meters in diameter before they would have a chance of raising the vehicle far enough off the ground to insulate it. This assumes no steel plys in those tires.

Otherwise a lightning strike will have enough voltage to ionize the air between the metal of the vehicle and the ground and jump the gap.

We were in a pretty good one in McClendon Springs BLM CG near Malta ID in May. It was amazing but I did start thinking about getting struck. We were about 20 yards from a big oak tree, but no other cover. I started thinking about lighting rods for campers and wondered if anyone ever set something like that up when staying in high risk areas. It would be a pain, but less pain than getting hit. We ended up not seeing any strikes anywhere near us.

I've been tenting twice and our campsite was struck by lightning.  My enamel camping mug has holes to prove it.  Scary sh!t.

Yikes. I hope there wasn’t any beer in it at the time.

nope, just water or tea.  We were hiding in an outhouse!  The hail was 2" across...

If you had been struck by lightning while hiding in the outhouse....................oh the stories all your friends would still be telling.

With all of the methane in an outhouse that could've been grim.

 

Wonder what lightning-struck beer would taste like?

If a sailboat survives a lighting strike, what are the odds a camper would escape unscathed?

Well we do not have sacrificial zincs on the bottom of the camper and I am not concerned if the camper is unscathed, but only if we are unscathed.   :D
