Ok, maybe on the west coast....GFCIs work by comparing the current flowing into the circuit via the hot wire and returning via the neutral, that's how they detect a neutral/ground short. because that current is "leaking" to ground instead of returning via the neutral. Without incoming current via a hot wire, the GFCI has no way to measure if any is leaking to ground, the means by which it identifies a neutral/ground short.
If a given circuit in the camper has a neutral/ground short, but that breaker is turned off in the camper, the house GFCI will not trip. Why? Because the breaker in the camper is stopping current from flowing into that circuit and revealing the fault by leaking to ground. Make sense?
What you're saying is equivalent to being able to find a leaky pipe with the water turned off.
