Trailer pops GFI's when plugged into power

[Dave B]

We have a new to us Sprinter. The good news is that all the electrical components seem to be working fine. The bad news is that when I plug its power cord in to any of the circuits in the garage where it will be stored, it immediately pops the garage circuit GFI. I've tried it on more than one circuit and they all blow, so it appears the problem is with the trailer. If plugged into a non GFI circuit there doesn't seem to be any problem.

I'm definitely not an electrician, but from what I can find out it takes hardly any leakage at all to trip one of these circuits. Since it's the main power line, it could be a nightmare trying to find what individual item in the trailer is causing this.

Has anyone else experienced this problem and does anyone know of a reasonable solution?
