Ground fault

I have a ground fault outlet on each circuit in my coach, but I keep frying the one in the bathroom. Happens when the circuit is over loaded usually by my wife's hair dryer. My question is why does the ground fault pop? The breaker does not trip. Could this be caused by the wrong amperage ground fault outlet?

A ground fault will obviously trip the GFI outlet itself.
Over current will trip the circuit breaker that's feeding it.
For some reason, using 15amp outlets on 20amp circuits is a common practice, acceptable and evidently legal, so a 15amp outlet being fed with #13awg wire and protected by a 20amp breaker, drawing close to 20amps and without fault, could very well do some cooking, without tripping anything and given that it's the weakest link in the chain.

If the circuit is 20A, it must be feed with wire capable of handling 20A, so commonly that means #12 romex. And a 15A outlet will only accept devices rated at 15A or less. anything drawing over 15A temporary or about 12A continous must have a 20A plug or be wired to a 20A circuit.

you commonly have a handful of 15A duplex outlets on one 15A breaker. running it from a 20A breaker is (or at least was) to code and very common. Allows more than 15A total draw, but no more than 15A from any single outlet or 20A from a duplex outlet.
