Surge protector on sale for south of border travelers

I can't count the number of times I have rewired an outlet in Mexico because of reverse polarity or just a bad connection. That is why I use my tester to check before plugging in. I also learned long ago that without some voltage regulation device a surge protector could be cutting off several times per day - if not constantly all day long. If you want to protect all the equipment today's RVs come with you have to be pro-active and use every tool available.
