I assume you mean you are reading 3 volts between Neutral and Ground on plugs in your trailer, or between neutral and trailer skin.
There is something that is causing some AC current to flow into the chassis (skin) of your RV instead of back thru the Neutral (white) like it is supposed to.
The ground wire from outlet to breaker box for a 15 amp circuit should be at least #14 copper wire which has a resistance of 0.25 ohms per 100 feet, plus there is resistance at connections as well. Voltage is current times resistance. Let's say ground resistance from the source of the problem to the main panel where ground and neutral are tied together is 0.5 ohms then the current flowing to make 3 volts would be 6 amps. Not enough to trip the breaker but A LOT of current going to ground instead of the neutral like it is supposed to.
THIS IS HAZARDOUS AND YOU NEED TO DE-ENERGIZE THE RV, FIND AND FIX THE PROBLEM.
