Voltage Drop - NOT Park Problem
Phoenix Cruiser 2551 30a service - First noticed it when A/C turns on then stumbles. Voltage at another RV outlet dropped well below 100. Capacitors good. A/C working fine until this point. A/C did...

Certainly sounds like a point of poor connection in your incoming power. V=IR or voltage drop is equal to current times resistance.. Example: if you had a poor connection of 1 ohm resistance with 1 amp current flowing thru it you would have a 1 volt drop, or loss, at that point. If you increased the current to 2 amps then you would have a 2 volt drop at that same point. That sounds like what you are seeing. You would also have localized heating at that point.
Looks like you have already covered all the obvious. You might look again at those connection points to see if crimps or clamps are partially on the insulation. Another possibility is partially broken wire. That can sometimes be hard to find as sometimes it happens inside insulation with no apparent damage.
