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
