First thing I would check is polarity on the outlet at the house.
House current is AC (alternating current). Impossible to be wired polarity specific.
A reversed hot and neutral connection is referred to as reversed polarity.
What happened to the OP situation is not to be taken lightly as it can kill. A 3 year old boy was electrocuted 2 years ago and an 18 year old boy in '11 by a hot skin on an RV.  Feeling even a slight tingle is not good. The OP should be absolutely certain that the cord indeed was faulty and something else isn't lurking.  Google "RV hot skin" for lots of info. Good older discussion on another forum 
here.  It's not uncommon for CGs to have bad wiring and pedestals and you need to be vigilant.
