You're basically trying to diagnose this from the wrong end of the problem. Instead of finding the electrical path of any power, first, establish ground continuity.
Here's the rules: Your RV grounding system should have a ground continuous to the frame from the load center. That ground should not be connected to neutral in the RV load center or anywhere else in the RV. The ground path should be continuous from the trailer load center and frame, through the shore cord, and to the receptacle that delivers power, then continuous to the ground of the load center, either on a pedestal or in a house.
As smkettner says, with the AC leaking current, you've found half the problem. The other half is to have an uninterrupted ground from the RV devices to the power source, the pedestal or the load center in your house. Every receptacle and device in the RV should show continuity to ground and you should be able to measure power from hot to ground when the devices are powered.
