If it's worked before, is your water heater on? The electric heating elements often begin to fail with a high resistance short to the case (ground) which will trip a GFCI. Also, if you're recently been in rain or washed the RV, water in the outdoor outlet(s) can trip a GFCI.
To troubleshoot it, I'd turn the main and all branch breakers off in the RV's power distribution center (breaker box). Now, does it trip the GFCI? If so, the fault is between the GFCI and the RV's power distribution center - maybe in one of the adapters or the shore power cord. If not, turn the main breaker on in the RV. Still OK? If so, turn on each branch breaker individually until you find the circuit that trips the GFCI. When it trips, you have the problem isolated to one circuit.
