I installed a whole house surge protector in the motorhome just to match what we have at home.
When we leave home we leave behind the lightning capital of U.S. so lightning not our major concern, much more in tune with the trees overhead for dead branches or since our run in with NUTS and the damage they caused. Falling nuts go right though sun aged A/C shrouds.
Did have a laugh last trip out, with a storm approaching the MH next to us was installing a 40 foot pole, asked if it was lightning protection or a ham antenna, neither a huge flagpole ;)
