If you don’t already have a surge protector for your RV, at least think about getting a circuit analyzer to test the shore power at your RV site before plugging your RV in.
In this quick video I show you a great device for ~$22 from NiLight that will save you a lot a troubles/headache, by only taking 30 seconds of your time.
Once you get to a site, use this NiLight Circuit Analyzer to test the power at your campsite. By doing this before you start your setup process, you’ll know your site has either a good or bad power source!!
