I use a circuit tester and a plug-in meter at the pedestal before I get unhooked at the site. If all checks ok, I proceed to unhook and get set up. The last trip, the tester was hard to see the lights correctly(in the direct sunlight). I thought it was reading a problem. So I took out my PI surge protector, plugged it in and let it do it's thing. All showed ok.
Even though a rig has been on that site everyday since the beginning of time, doesn't mean the pedestal is wired correctly.
Check it out. You paid for the rv, not the campground.
