I have a 30 amp RV. I made a quick outlet tester out of a standard 3 light tester plugged into a 30/20 adapter. Cheap, quick, and pretty much fool proof.
Same, and I also added an inexpensive device that gives a voltage reading. I use the three light tester first, then check the voltage.
Last August we stopped at a camp in Barstow CA that had voltage fluctuating around 103-107. All of the available sites had the same condition. Thankfully we were able to find another campground nearby and original host refunded our fee.
You know what I love about that volt-meter, is when using it to measure inverters AC output, it will show you a pure sine wave vs modified sine wave, I keep it around just for that reason and use a different one with a clamp for most other things.

Exactly!
