There is a plug in tester at camping world that seems to offer all the
informatiom you need. Voltage Frequency Amps and polarity. It didn't say
how many amps though. One thing though. Ant testing you do should be at
the power pedestal BEFORE you hook your camper to it. That means you need
to use an adapter to convert from a 30A receptacle to a 15A
receptacle.


The only problem with that .... John ... pay attention..... is that if
the RV site's wiring or power is lacking, it will not show a voltage droop
with any load. In other words, the voltage may read 120vac under no load,
but after he plugs in and fires up the AC it might droop. He can find out
by measuring the voltage before he hooks up and then again with the AC
running at any 120vac outlet in his camper, assuming it is not powered by a
converter. Usually the microwave and the AC are not run through the
converter, so either of the power sources inside the camper could be
checked.

The voltage at the remote power setup I had in Florida used to droop to
105vac on some days. Bad for the AC compressor. That's why I bought the
buck/boost transformer.

There's a difference between "Droop" or sag and voltage drop under load.
The sag can be detected without hooking up a load.
