After a battery
charger had meltdown I carry one of those economical little outlet testers and check the campsite source before I plug in. I have found the camps wiring wrong on a couple of ocasions.
"Oh it's OK just go ahead and plug your trailer in.
Then You'll pay for any damage done to my trailer, Right?"
Now that you bring it to my attention, it would be a good idea to replace at least the original household type outlet on the outside where we connect a coffee maker or electric frypan with a GFI. BUT then I'm sitting on rubber tires
, isolated from a true ground except for the camp ground. Mabee a surge protector would be better. I think I need an electrician.
