Is your water heater powered by the appliance circuit and does it have an electric element? The elements in a water heater are notorious for this as you can't see the problem and it can trip the GFCI if it's bad. If that isn't the situation, you'll have to trace back from the "appliance" breaker and see where you either have a short between ground and neutral or hot to ground.
Do you have a handheld meter? It makes diagnosing problems much easier.
One of the first places to check is inside the AC load center on the trailer and make sure all wires are clamped and not oxidized and that neutral is not tied to ground anywhere. Another good place to check is in receptacle boxes. If you have RV style receptacles with the guillotine connectors, those are also notorious for causing problems.
If you can get a hold of a meter, there are specific things to check that will make diagnosis easier. In the end, it will probably be one small thing.
