here is what happens in our rig when plugged into ANY GFCI.
Plug the rig into GFCI outlet (mains) when the breakers to the two GFCI protected circuits in the rig are on, the mains GFCI trips. Unplug from mains, turn off the two house breakers, plug in the mains GFCI, and all is well. Drove me nuts until I found this out.
If I read this correctly, the pedestal (mains) GFCI trips whenever your RV GFCI breakers are on, but the RV GFCI doesn't trip when you plug into non-GFCI protected power.
It's possible for two GFCIs installed in series to to interact, although its relatively uncommon. You might try replacing the RV GFCIs to check this.
It's possible you've got problem that's not sufficient to trip the RV breakers, but does trip the pedestal/mains. You could try temporarily replacing the RV GFCI with a normal breaker. If the pedestal still trips, you have problem on that circuit that the RV GFCI can't see.
It's possible you have one of the less common situations where turning off the breaker after the GFCI prevents the GFCI from tripping, although, I'd expect the RV GFCI to trip in that case. You didn't really say if the RV GFCIs ever trip.
