Evidently you have not camped in Trail of Tears State Park, MO. ALL receptacles, 15, 30, and 50 amp are GFCIs. I've stayed in one other Missouri state park that also had GFCIs on all the receptacles - maybe it is all of the state parks...
It is worth taking the time to find what is causing the trip & fixing it. Bobbo's description of finding the fault is a good one, although I'd start with checking the adapters first.
