Does it trip the GFI with the air conditioner circuit breaker turned off? If no, there's leakage between the hot (black wire) and chassis ground in either the wiring or the air conditioner itself. If yes, there's leakage between the neutral (white wire) and chassis ground in either the wiring or the air conditioner itself. Disconnecting both power wires at the air conditioner should tell if the problem is in the air conditioner or the wiring to the air conditioner. To be safe, just pull the shore power plug before working on the connections. If you're not experienced with 120 volt wiring, leave it to somebody who is.
