I also use a portable surge protector. I had a 50 amp protector in my last motorhome that I kept when I traded it in. A friend had a 30 amp that he bought before getting his new 50 amp 5th wheel. Since I wanted the smaller, lighter 30 amp and he could use the 50 amp, we traded protectors. Now both of us have the correct protector for our rigs. I found that at some campgrounds I don't feel I need the protector, but at other older campgrounds or the weather is bad, I will hook it up. I guess I should hook it up all the time, but I get lazy sometimes. On the last motorhome with the 50 amp, I found it did cut off several times because of low power. Low power occurs when to many rigs are plugged into the circuit and running to many a/c units. This is more of a problem at older campgrounds that did not install the required electrical circuits for todays load. Low power will cause your a/c compressor and your ciricut boards to burn up. A surge protector is cheap insurance compared to replacing an a/c, microwave or frig.
