SunSport,
In general the appliances listed on page 15 of the very generic "motorized owners manual" from Gulf Stream need to have 110 volt AC power to operate.
If you don't yet have this minimalistic manual it can be downloaded in PDF form at

Although it is very non-specific regarding any particular model of moterhome, it still contains useful information...
110 volt appliances can be operated from shore power, your generator, and in the case of small appliances from the inverter if you have one.
My coach is substantially different from yours, and it has multiple TVs only one of which can operate from the house batteries.
A 10-cup domestic coffee maker is an electrical heating appliance that can consume from 1000 to 1500 watts and only operates on110 volt AC supply. A compact coffee maker (4-cup) is about half that wattage but still runs on AC.
Hope this helps...
