An RV is nothing more than an electric subpanel. You carry hot(s), neutral, and ground to the RV's panel.
If the OP's house receptacle tests properly and has all three wires properly connected (thus testing properly). then (and only after the proper GFCI has been installed) plug in the extension cord that was used, and test it, If the tester still shows OK, then hook up the adapter and the RV and use the tester on the RV's various outlets to test each one of them.
Then start looking for individual items that can cause a hot ground. My bet is the 120v heating element in the fridge (if turned on), as they can easily short to ground, or the water heater if turned on using 120v.
Just recently I read a thread (cannot remember what forum however) that the OP had discovered a hot skin condition and traced it to the 120v heating element in the fridge. He replaced the heater element and installed a plug in GFCI in the outlet behind the fridge and plugged the fridge into it. I'm not sure I advocate doing this however, as GFCIs are electronic and mechanical devices and the vibration of going down the road can cause the GFCI to trip, and then your fridge won't cool and you don't realize it until its too late.

Note: should you happen to purchase this particular unit, the instructions refer to a "light" that comes on when it trips. It is not a light at all, but rather a red flag that appears in the tiny clear window on the unit above the buttons.
