Having trouble understanding GFCI problem
I have my MH in a storage lot with low capacity electrical hookup for battery charging. Three of us are hooked into one box. After the initial bulk charge for a few seconds mine drops off to below ...

All I really want to know and it's still not quite clear: Will a GFCI breaker trip, strictly due to over current and is there an obvious malfunction with the breaker, considering that any on of the three units will cause the trip?
Pianotuna's idea of stacking one RV off the other may be interesting. We don't have any outside outlets but I may try plugging my nextdoor neighbor into one of my receptacles to see what happens.
A GFCI breaker (as in one in a circuit breaker box/load panel) is both a GFCI and a circuit breaker, and so it will trip from either overcurrent or from a current imbalance between the hot and neutral lines, which indicates leakage somewhere.
A GFCI receptacle is not a circuit breaker, and will not trip due to overcurrent...but it should of course be protected by a circuit breaker upstream.
The breaker is not tripping due to overcurrent; you're consuming very much less than its rated capacity. Logically, it must be tripping due to it thinking there's a ground fault, apparently due to accumulated leakage current. You might be able to prevent the tripping by shutting off the circuit breakers for all. the circuits in the RVs you aren't actually using--which presumably would be most or all of them other than the converter circuits.
(I'm wondering why this place has 20A receptacles protected by a 30A breaker, but as I'm not the local electrical inspector I guess it's really none of my business.)
