Battery charging from shore power?
Stock, do most trailers charge the batteries when they are hooked up to shore power? Or does that occur when the trailer is hooked up to the tow vehicle?

You can guess at that, but you really need to see the amps to the battery for each method over some time.
It is not a guess.
A higher voltage measured AT THE BATTERY will charge the battery more/faster.
You also have to consider the amps the power source can supply, but given that those are equal, I am unsure who is right here.
You don't need to be unsure here at all. If the supply can't provide the current that the load wants, the voltage at the load goes down.
You are trying to make it too difficult: A higher voltage applied to a battery will charge it more. If the charger cannot supply the necessary current to do that, the voltage will not BE higher.
