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.
Even if you added a ground, you'd have to drive about an 8 foot rod into the earth. The rod won't come out easily and if you camp a lot and drive a rod every time, it will get expensive. I don't worry about it - the shore power ground is good enough for me.
