I have seen GFCI's trip when there was no problem, In fact odds are if I were to visit you I could trip yours without touching anything electrical in your RV including the GFCI... I wont' say how. but I could easily trip the GFCI in a neighbor's RV if I wished.
That said. Yes. it is good to know what tripped it. Some indicate need for repair work, some it is operator error, as my wife once proved. (no harm due to GFCI).
If you are near Oconee Co, SC I can likely help with a few things.. Or some other forum member no matter where you are.
