Further to Mac's and Rob's comments, I know of an incident where some home
entertainment equipment was destroyed when lightning caused an intense
overvoltage condition. Fortunately, the destruction was limited to, in this
case, a then-expensive DVD recorder/player. It did not ignite the cabinet
but did cause heavy charring below the device.
All other items on that circuit survived with no damage.
It could be that an argument could be made that owners should disconnect
from shore power with signs of an approaching electrical storm (or at least
trip the AC breakers inside the coach?)

Lightning, similar to tornados, does weird and unpredictable things!
The advice in your last paragraph is definitely worth following!
Even though I have static electricity discharge devices on each of my ham radio antennas, I still disconnect them when I KNOW thunderstorms or coming or I'm going out of town.

Fred's suggestion to unplug shore power is a good one (which I've never
followed), but I don't think tripping the breakers would be worth the
effort expended. A lightning strike would probably jump that tiny gap.
Similarly, turning off individual items is probably worthless -- unplug
them if you're worried.
But, in the final analysis, lightning's going where it wants to go. A
close friend who was a USAF meteorologist had an assignment investigating
lightning strikes. He tells the gruesome tail of an individual riding in
the bed of a 2-1/2 ton truck. Lightning passed through the large tire, the
metal bed of the truck, the individual, and took the top of his head off.
That tire SHOULD have been a pretty good insulator, but it wasn't good
enough.
Another EE friend accused his small son of somehow chipping the Formica on
his desk top. When he found the telephone, beneath which the hole was
hidden, inoperative, he investigated more closely. He found, in addition
to the crater in the Formica, a tiny brown spot in the tan paint on the
metal desk leg where there had been an arc to a nearby wall socket. The
computer on the desk, plugged into the same socket, had an inoperative
keyboard; there was no other damage.
I don't think I've ever been as frightened in my life as I was when caught
in an especially violent thunderstorm while on Holmes Creek, FL in my
canoe. No place to hide except ashore hugging one of the huge trees --
would that have been safer than just laying down in the canoe? A very
scary 30 minutes!
It's a capricious phenomenon.

After a bolt has already jumped several thousand feet, the distance across a tire is inconsequential.

What's a thunderstorm? Here in God's country, we hear an occasional rumble
off in the far distance. Very seldom any lightning strikes. In Eastern
Oregon, different story. Lots of range fires start with dry lightning
strikes. Supposed to be 100° here today. No rain since June 6, 2015.

I've been told and believe that any voltage spike large enough to start a fire would jump the contacts in an open breaker like they weren't even there.
I'm surprised there was not damage to the power distribution panel for the shore power or other things connected to it.
I'm with others though. I've seen lightening do bizarre things. We had a strike about 100 yards from the house that exploded a 8" PVC water main buried 6' down. Blew blue PVC for 50 feet in all directions.
