Can i, or should, I ground my trailer with a grd. rod to frame,even if my rv shore cable is grounded thru the rv recepticle box? My trailer is permenent on its site.
I don't think lightning is a valid concern as a reason NOT to ground. First off it is already grounded through the service connection. Secondly, if the lightning can travel many miles from the clouds to your RV, a couple extra feet to the ground isn't an issue.
