I have a 24 foot C and we have a sure guard unit hard wired at the point where the cable comes in and all electronics are hooked to a 10 watt line conditioner, never had a problem in the USA or Mexico, one thing that we do have is the wing antenna, the CB antenna, the roof air condition unit, solar panels and the rear ladder are bonded to the chassis and I made sure that everything metal was also bonded including the outside compartment doors, we also have 25 feet of multi strand electric wire with clamps and I carry small metal tent pegs to insert in the ground, they are cheap enough to leave if I can not pull them out, granted not the best but there is a path to ground with some water around the peg.
I really hate getting zapped by stray current, I did notice that when the ground (green wire on the outlet) was not hooked in the house or outlet, that is when the zapping occurred, so I started experimenting to see how I could alleviate the situation, a dedicated ground to the chassis cured that and I tested all the metal around the unit and bonded them.
Why bond the ladder, we had a lightning strike the ladder in Arizona in a thunder storm before it was bonded, made a pin hole where it hit and where it exited after that we decided no more surprises, lightning is unpredictable and that is the desert for you, then we had to peel the cat from the ceiling.
