A 2K inverter can draw 200 DC amps, your coffee maker will draw 75 DC amps. A 100 AH battery can deliver 50 AH's of service. It is unlikely the 2 GC batteries will reliably completely brew your morning coffee given the RV has been drawing current all night & evening.
The above #'s are simplistic rule of thumb for easy in your head calculation.
I would recommend a stove related brewing solution. (That's camping)
760W @120V from a typical 90% efficient inverter is (760*1.1)/12 = 69.6 Amps
need more coffee ? :B
