Rudy -

Did you ever solve this problem?

While doing some work on my TM, I ran into a situation that sounds like yours, and I SOLVED THE PROBLEM! It seems that the negative side of the 12-volt power system is connected to the trailer frame (and hence all the sheet metal, etc). However, the ground wire in the AC (shore power) system is isolated from the frame. If this AC ground touches the trailer metal, the GFI in the shore power system would pop.

In my case, the unwanted point of contact was in the back of the converter, where a long unsupported ground wire was moving around slightly, and making intermittent contact. Just stepping into the trailer caused enough motion to make momentary contact - and POP!
