GFI supplied power

Has anyone had a problem with their TM tripping a GFI breaker? Power was supplied via a GFI breaker at a campground this weekend. I could not get power from the campground because my TM power chord tripped the breaker each time I tried to plug it in. The campground electrician replaced the breaker with a new GFI breaker, but the problem persisted.

The odd thing was that sometimes I could get the power to work through the GFI breaker for about 10 minutes at a time. Then the breaker would trip. I finally gave up and used my battery for power.

Also my switch under the back wall of the shower kept tripping. I would have to move the shower wall back and forth to get it to switch back on. Were the two problems related?

Any solutions?

Thanks in advance.
