Yes the breakers only isolate the hot, but the GFCI won't trip with the hot disconnected. Some things in the camper you can't "unplug", items like the converter and HW heater are usually hardwired.

Not true. GFCI’s can absolutely trip with the hot disconnected. They can test for and trip by simply having a neutral to ground short without any current flowing. So while turning off breakers may reveal something, it may not.

To completely isolate, you may actually have to open the camper panel and disconnect the neutral wires until the fault clears.
