I guess I need to open up the hardwired ems and take readings there to get a better understanding.

Have to do this at home hooked up to my 30 amp supply and see what I get.
Yep, you might be worried about nothing. But it's good you understand enough to know there is something different.

Just to flatten the playing field, I'd hook all those measuring devices you have to as close to a common place as I could and see what they read.

It wouldn't surprise me if they were all off a little.
What is the brand of multimeter you have?

You will need to have the same load on the circuit when you take all of the measurements. When you have no load the voltage will be higher. As the load increases and the drop across the extension cord and other items increases the voltage will drop. Since you measured the house outlet with no load it would measure higher voltage. So I do not think you have a problem here other then the low voltage to the RV. Your EMS is just doing its job and protecting you from low voltage than may harm your AC or other electronics in the RV. I would not run AC items with a voltage below 110V but that is not the setting of the EMS.

More than likely I am concerned about nothing.

Left Son's place yesterday early morning. When I looked at the EMS reading it was 114volts and no errors. When we got home yesterday I hooked up to my 30amp. Reading of the EMS was 121.

Today I am showing 122 from the EMS. All looks good.

So, really no problem. This does show me that a 12gauge extension cord really does not provide the consistent good quality power that one would want in there MH. Also it has proven to me that an EMS is really an essential item for your RV investment.

Thanks all for the suggestions and comments
