Mine triped the 20 amp GFI whenever I ran the generator, and then turned off. When it transfered back to shore power the GFI would trip. Replaced the GFI with normal outlet and no problem since. So there answer of Ground and nuturl together sounds resonable.

Here is a link to my suggestions for finding the problem: RV trips Campground GFCI. Again, if you are not happy sticking your fingers in your electrical panel, call an electrician for ground/neutral faults...
My electric hot water heater will do that...if I disconnect the ground on the heater it will not trip...works fine on the gen with the ground connected.
This is usually the result of a damaged heater element. A fault has developed between the neutral end of the element & the water (which is at ground potential) resulting in a ground/neutral fault. Replacing the element will probably fix the problem...
I just had that problem this weekend when we went camping. I got to the campground set up the camper and plugged it in. A few minutes went by and the lights started to dim and then the breaker on the outside pole tripped but nothing inside the trailer was even on. I checked everything for almost 2 hours fridge, water heater, furnace. Finally I figured out with a little help from the campground host that the house battery inside the camper was bad and I mean really bad because the converter in the camper was trying to charge it and it couldn't, so it was drawing a ton of amps from the pole and it was popping it. I went to the Kmart down the road bought a new deep cycle put it in and we were good. I never thought the battery even mattered because I had the camper plugged in. Check your house battery to see if its taking a charge well. Or maybe see if the converter that is charging the battery is good. I was popping the pole breaker all year when i had too much stuff on at once but never did that before. Just thought i would share my story to see if it would help.
Got a portion of it figured out. We went thru all the breakers and the WH and Cargo areas seem to be the problem. The Water heater element is bad. Turned to local switch off and it is no longer tripping the GFI breaker. Now what could possibly be in the cargo area that would cause it to trip....

Something plugged into one of the receptacles? identify item and remove. dteremine why it is causing problem.
Water or corrosion in receptacle? Take each one out, inspect and clean.
There have been previous posts about bad adapters. The adapter is used to allow a 50 or 30 amp trailer power chord to plug into a smaller outlet. Since you indicate that the campground or house GFCI outlet is tripping, then you must be using and adapter.
Test the adapter with a multimeter. Test for resistance or continuity between each of the 3 prongs. If you read anything other than "Zero" the adapter is your problem. Take the meter with you to test the replacement you are thinking of buying. Also check to see where the adapter was manufactured, since not all countries of manufacture use the same standards.
Other simple tests:
Plug the adapter alone into a GFCI outlet. Does it trip? If so, replace it.
Plug the adapter into a GFCI outlet. Take your camp power cable to the GFCI outlet and, without the cable being plugged into your trailer, plug the cable into the adapter. Does it trip? If so, the problem may still be in the adapter, but the cable is also suspect. Start with replacing the adapter before considering replacing the cable.
