before and after below
The good news is I looked around and found a plug on a different breaker, and turning the heater on, on a different breaker, did not alter the volt meter reading at all.
We would have never known this was happening, except we keep a volt meter plugged into a bathroom plug at all times
You have a resistive leg. The problem could be in your RV, cord, plug, 50 A receptacle you're attached to, breaker feeding the receptacle, etc.
You say you are full timing. In one place, or does the problem show in multiple locations?
Might want to avoid using a receptacle that causes the drop until it's fixed, since some heating is occurring at the resistive point.
