Also be sure to cut off your ice maker, that draws power when it goes into the heat cycle, when harvesting the ice cubes.

UPDATE: I did just what you suggest and upgraded to a Xantrex Freedom X 2000, and now the fridge works! One thing I did notice, the evaporator fan in the freezer was slowing down and eventually stopped, so I replaced that as well. This may have been drawing a larger load than the old inverter could provide. While I was replacing the evaporator fan, I completely removed the ice maker and turned off the water supply to the fridge. If we need ice, we just put some in a gallon ziplock bag and throw it in the freezer for the trip, way easier!
Also, @Connieb, yes, this coach behaves strangely vs. others I've owned in the past...
-> Strange Behavior #1: The chassis (engine) batteries are under a fair amount of load when the house master switch is ON. Backup cameras are powered, armrest lights are on, and the ding-dong-ding tone when you open the driver's door, etc. It's like the ignition key is in, and turned one click to "ACC" for the entire camping trip. Plugging in to shore power or starting generator does not charge the chassis batteries, so they are nearly completely drained when we leave to go home. Starting up the engine for several hours every couple days during our camping trip is not a viable work-around.
-> Strange Behavior #2: I tried to remedy the above problem by just disconnecting both chassis batteries, but when I checked voltages, I found the voltage between the NEGATIVE battery terminal and the frame was 12V! Should be 0V. Any experience with this issue?
