If everything is okay in your RV, and it should be as new as it is, I would suspect the outlet you are plugged into is wired wrong. Do you have one of those little 3 light plug in outlet testers to test for ground continuity and reverse polarity? If not you should get one at a hardware store, they're cheap. Do you own a voltmeter? You can use a voltmeter to check the outlet too.
Can you try another outlet? Can you run a long cord to another outlet just for troubleshooting?
Also, with the RV unplugged, inspect your shore power cord for damage. With the RV plugged in turn off the circuit breakers and see if the sensation goes away. It may be just one circuit in your RV that has a ground fault in it.
