Will GFCI work with items without equipment ground
I know it's probably a dumb question but my wife's hair dryer is old and has no equipment ground. Wanted to be sure she is still protected if it should be dropped into water or otherwise shorted.

All this brings up another related topic. I know I'm wavering.
My RV is in a storage lot where a, low potential, outlet is supplied for each camper. An AC unit or electric water heater will immediately trip the main.
We, pretty much, only plug up to keep batteries charged. Nobody loads anything of consequence on the inverter or 12 volt system.
Every motorhome owner I talk with seems to have a persistent problem with the GFCI's tripping. The only thing we all have in common is that we all have an inverter. Mine is a 1500 watt Xantrex PSW.
Is there something inherent with motorhomes that could cause this? I know the 15 amp connections an campgrounds are GFCI, but I doubt they are used by motorhomes.
Read ktmrfs post above (very good post) and note the last paragraph. If the inverter has the neutral/ ground bonded and its transfer switch defaults to the inverter, before the switch can transfer the gfi will pick up a neutral to ground fault and trips. This use to be a problem years ago but I thought the inverter manufactures had solved it, but maybe not. It could also be the inverters were not installed properly.
