3 weekends in a row, EMS tripped each time

To be honest, I don't entirely understand why RV receptacles aren't required by the NEC to have GFCI protection.

I can think of several reasons why it wouldn't be a good idea.

Your motor home is plugged in to 50 or 30 amp service that has GFCI built in. You leave for the day in your toad and return late that evening to discover that the GFCI tripped shortly after you left, and your rig has been without power all day.

All the food in your refrigerator and/or freezer is now warm.

Your dinner, which was left in a slow cooker, is not only not cooked, but it's probably spoiled.

You left the A/C on because you left your dog/cat(s) in the motor home and rather than being safely cooled all day, they've been locked in an oven.

We wouldn't want our sticks & bricks to be on a master GFCI, we want the option of having some circuits, like to our furnace and our freezers to be on non-gfci circuits. The same logic applies to our mobile homes.

My fridge would just switch to propane. A lost meal is a small price to pay for electric safety, in my opinion. Pets are a reasonable concern for some people in some areas; presumably in those areas, one ought to have some other backup system in place in case of an ordinary power outage from whatever cause. (Most of the places where I camp, towards the northeast, the interior of the RV would not get too hot for a pet without air conditioning provided there was fresh water available and some ventilation. I rarely use the air conditioner myself. I do of course understand that e.g. Arizona is entirely different!)

If the GFCI trips, there is (most likely) an electric fault with the RV, and quite often one that is potentially dangerous. I could see having somewhat relaxed trip current requirements for RVs since it's reasonable to expect more leakage current. More than one RV is around with a fridge or water heater element that leaks current to ground, and the owners know nothing about it.
