I agree with Mr. Mark. My coach has the same setup as his, which I believe is the same way the MA is configured as far as power goes. The fridge (mine is GE) is head and shoulders better than a gas refrigerator. Cools better, runs quieter, and has much more space inside. I never have to think about settings or whether there is enough propane, because I don't have any.
I was nervous in the beginning about boondocking but I have done some of that now and as Mr. Mark says, 2 hours morning and night on the genny and you are golden. The refrigerator is amazingly efficient. Most of the electricity useage is from us, not the fridge. If the coach were unoccupied I am sure the fridge would go 24 hours or more before the auto gen start would kick in.
