If your only service panel is 100amps and is going to supply your 50amp RV receptacle and the rest of the house combined then you may need to upgrade it to 200amps. If your 100amp garage service panel is a sub-panel of a larger capacity panel you are good to go.
Not required. Upgrading the service is not a bad idea, it just can get very pricey very fast !
You can feed a sub-panel with half the current of the main panel. So if he's coming off a 100 amp main 50 amp sub is okay.
