Most likely your propane refrig requires 12 volts for the control panel, so using the disconnect will cut power and the refrig will shut down. You could add a small gel cell at the 12v connection inside the panel at the rear of the refrigerator which would maintain power to the control panel when the disconnect is used, but does require a diode to stop back flow from the gel cell. It is also a useful modification when precooling while the coach is in storage. Your plan to close a slide while gone would be helpful if you run the generator while opening and closing.
