We still do the same ... when boondocking, we jealously hoard every last milli-amp-hour of the batteries for the fridge and furnace.
Regarding the OP

I just checking the power that my Crock-Pot consumes. 2.25 amps, 278 watts.
My question - will my RV batteries be able to sustain that kind of power for 6 hours?
That is a huge draw on the batteries, as all the math preceeding this point makes.
Here is a "trick" we used successfully ... may or may not work in your instance ...
We prepared a crock-pot and used an inverter drawing off the TV electrical system. Since it was a several hour drive, we were able to leverage that cooking time and show up with it steamy hot.
Realise that this doesn't so much help if you are parked for many hours before serving time, but it is a way to leverage the power available while the wheels (engine) are turning.
