[VAL] fuse box / grounding questions

RE: 1971 LY Safari 23 - rear bath, twin beds

I am new to Airstreams (as I have said many times over ... ) but I do know
where the 110 fuse box is (rear port-side closet)

Question #1 - I sort of know what the GFI in my HOUSE does (it makes sure
the patio outlets and bath outlets "break" in case of dampness/water) ... so
what is the purpose of the GFI in my Airstream? Assuming it functions
correctly, does it protect me from shock in case of damp/wet conditions
where my trailer's "shore power cord" connects to the land outlet? (or where
there might be any damage to the cord itself)

Question #2 - how do I tell if I have a GFI breaker? How do I know it works?

Question #3 - how do I know what size any of the breakers are and how do I
confirm that rating?

Question #4 - when somebody refers to an electrical outlet/switch as being
grounded, is that the same as GFI?

I notice that dust etc. sticks via static electricity to the hard plastic
housing on my compact vacuum cleaner. Is this necessarily indicative of lack
of grounding? Or is it indicative of the climate (dry, 12" rain per year)?
OR ??? (It is not unusual to experience static shock when wearing rubber
soled shoes and touching car door, for example, in this same climate.)

Clearly, I am a novice when it comes to BOTH Airstreams AND electricity.
Scarey thought.
