Nice looking set up.
I use a plug in meter to monitor voltage and Hz. Have it plugged in inside the coach so I can monitor it easily.
In addition, I have a Progressive 50A surge protector hard wired that will drop out at any time if there is a power problem. It also has a remote readout mounted inside that indicates what the problem is should it drop out.
This one has paid for itself more than once. And, lifetime warranty. Google progressive surge protector.
