Because it trips INSTANTLY at home but not at camp grounds, I think it’s most likely that you have a grounded neutral in motorhome. It’s a common problem and fortunately one that is very easy to check.

If it is a grounded neutral, opening all breakers in your motorhome won’t keep your house GFIC from tripping. If house GFI trips anyway, you can confirm motorhome neutral is grounded with a multi-meter; or ask shop to check for you. Just takes a minute with OHM meter to confirm if that is indeed the problem. Could be many things that is causing your problem, but I would bet on it being grounded neutral.
