Someone here mentioned having a 120VAC PLUG-IN AC VOLTMETER.
I have one of these plugged into a inside receptacle somewhere in the trailer where I can glance at it. This is is neat as it has a "GREEN" safe zone marked on the scale. If the 120VAC is outside of this "GREEN" safe zone tells me the AC Voltage may not be safe to use especially when turning on the Air Conditioner. These are not absolute readings but will give an idea of what is happening... I got mine from AMAZON but these are probably available at your local RV parts places..
