in most cases, a 'master' GFCI OUTLET is located in the hall bathroom, and it also 'controls' the other outlets on the same circuit, which is where the confusion can be had.
A GFCI outlet that controls other outlets on the same circuit is basically acting as a 'mother' outlet, with the same GFCI sensor function with each of the other outlets. When a moisture or other related symptom arises, any of these outlets can cause the master GFCI outlet in the bathroom to TRIP itself. This trip, though, is not at the breaker in the main electrical panel, but at the outlet in the bathroom itself. It didn't trip due to an overload, but because of the moisture or related issue.
Generally, GFCI master outlets control other outlets that are in similar places of 'concern' within and outside the RV, such as the Kitchen(near the faucet, water), and outside(water, rain), even if the outside outlet is within a compartment or storage bin.
Of course, a circuit that contains a GFCI outlet can trip, due to overload, just like any other circuit, but then the BREAKER at the master electrical panel would need to be reset, not the GFCI outlet itself. This is when you know you have too many things going on at the same time, drawing too much power. If it's just due to a moisture or water issue, it could happen just by plugging something into a GFCI controlled outlet, like you experienced here, whether or not any other things are actually being 'powered' on the circuit.
FUN, hunh? !!
