The extension cord is only one part. There could be a problem with the pedestal plug, the RV cord or wiring or for some reason the RV frame or other metal parts are not grounded.
Furthermore both the hot and neutral should be isolated from ground in the RV and reverse polarity doesn't change that.
You may want to rethink your premise! "RV frame or other metal parts" not "grounded" are typically because the neutral and hot wires are reversed. Keep in mind a properly installed neutral wire is always grounded at the main panel. If the neutral wire is properly installed, the RV frame and metal parts are GROUNDED! If the neutral wire is not properly installed, such as reversed polarity, the frame is probably NOT grounded and in this case, the hot wire is probably connected to the frame. The OP has to find the reversed polarity hot and neutral wires.
With a properly installed hot and neutral wiring system, the green ground wire is redundant, meaning it is not necessary for a safe, grounded system. It is an additional safety measure, not the primary one.
