Yes, seems to me like a bad ground connection in your shore power drop.
There was a thread not long ago on another forum not long ago, don't think it was here..... the guys was talking about this very thing.

We sold the fifth wheel and now have a motor home and have not had that problem since. Someone advised me to always use something insulating between the ground and your steel leveling jacks as lightening strikes near or in the ground can travel up them. I always do that since being advised of it. Sounds like a good precaution. Myth or fact, I do not know. I'm not an Electrician just a Guy out there RVing and taking advise when I get it.

I always figured that if lightning has enough energy to travel 40, 000 ft or more through the air, it won't be stopped by a set of tires, or in this case, an inch of plastic. The reason you are generally safe in your car in a lightning storm is not because the tires insulate you from electricity, but the car acts like a shield... i.e. Faraday Cage.

At any rate if there is a voltage difference between earth ground and the chassis that is tripping the GFI, and if it is the result if mis-wiring, you could potentially get a shock when you step out of the coach onto the ground.

I don't mean to harp on this, but it could potentially be a safety issue. Enough that I would feel better if I got it checked out by an electrician... especially given the quality of work that we are accustomed to in the RV industry.

As I said though - potentially an issue - but not for certain.

Like I said that fifth wheel is gone. Our new motorhome does not have that issue when plugged into the garage anymore. The GFI doesn't trip with this RV when plugged in whether the pavement is dry or wet, although I still use the plastic blocks as I don't like the leveling jacks directly on the blacktop. Can't tell you why the fifth wheel would trigger it but it usually did it when the pavement was wet and once I used something with an insulating effect between them I was fine. Anyway that's gone and I still use the plastic blocks. Your probably correct too about the voltage of a lightning strike you may just be kissing your electronics away if that happened.

I visited the Bigfoot plant today and checked out their levelers. I am definately going to have them installed. I did find out they usually have a special deal in Jan with up to $500 off installation (normally a $600 flat rate). So we'll probably tough it out for whatever remains of this RV'ing season and have them installed prior to next Spring. Gotta pay for the toad setup first.

What I like about them is the jacks work in pairs. This keeps the jacks "equalized" when they contact the ground so they don't stress the frame. Still not sure yet if we will go with the manual or automatic system yet.

So i take it that the HWH system doesn't work in pairs then..... sorry if that seems like a dumb question, i just haven't had the time to thoroughly research on my own yet, so I'm benefitting from what has sold you one way over the other....
thanks for that!

That... I don't know.
