Here is a 50 amp tester that I check the power pole electricity.  I built mine 18 yrs ago and use it every time prior to plugging the coach in.  It has saved me three times.

Thanks Steve! I was just about to buy one of these - probably saved me $300 or more! The last one I bought got stolen! Do you leave this plugged in at the site or do you just use it when you arrive and for spot-checking voltages at the pedestal?

Leave it plugged in, guarantees no power issues.

Nice job Steve!

You might try to see if two of these will fit.
