15 and 30 AMP "Y" Adapter to 50 AMP

Probably only needed on old systems anyway. Only time we have used ours was on in an older campground where the 30 amp was dropping voltage during the day.

Will not work. :)

How to make it work on a GFI outlet?

Sorry, they will not work on a GFI circuit. You are going to need 2 30's or some really old wiring connections where a GFI is not part of the circuit anywhere on that line. We are not talking about the GFI in the coach but rather the circuit you are trying to plug the Y into.

The GFI (ground fault interrupter) outlet in your RV is not dependent on the 120 volt power plug adapter's, unless you have disconnected the ground or crossed the wires somehow.

The adapter should allow 1/2 of your RV to be powered by the 15 amp source and the other half by the 30 amp source. Fifty amp power means the RV has two circuits that can draw 50 amps each, but they are not "combined" since that would give you 240 volts, and that would destroy your RV's electrical system. (That is, unless you have a VERY high end coach with a 240 volt system.)
