I too have a travel trailer, and use a surge protector. In the older campgrounds it is not unusual to find and open ground. I have only run across reverse polarity a few times.

Boats have good electrical panels with volt and amp meters. There is also a reverse polarity indicator on the panel. I have run into low voltage at a few marinas. One case in particular was Light House Marina in Hope Town on Elbow Cay. I checked to voltage to the boat, and the meter read 91 volts. Too low, so I disconnected my power chord. It didn't improve. So, rather than pay the higher marina fee I moved out to the mooring field. With all the expensive electronics on a boat I can see where a surge protector could give peace of mind.

Fortunately, I can go long periods on my boat and RV without the need of hookups.
