Really dumb extension cord Q
I believe I know the answer but want to get some clarification... If I am to use an appropriate size 15/20 amp extension cord (10 gauge) for shore power but am adapting either end up to the 3 prong...

The lowest amp rating part of the cord will determine it's maximum current rating. If you have a 15/20 amp plug on one end, then it's a 15/20 amp rated cord. It's the old "weakest link" maxim...
Yes, and if the WIRE is the lowest rated part, THAT will determine it's maximum capacity. So if you take a 20 amp extension cord and cut off both ends, then put on 30 amp plugs, you still have only a 20 amp extension cord. If you try to run 30 amps through it, it is going to get hot, maybe even to the extent of catching fire.
Absolutely! In the OP's case though, the 10ga wire size is correct for 30 amps, but the 15/20 amp plug isn't.
