2015 Thor Challenger Residential Refer

A friend of mine purchased a 2015 Thor Challenger. It comes standard with a Residential refer and a Xantrex 1800w inverter running off 2 6v deep cycle batteries, as well as a rudimentary Magnum Autogen start. The problem is that the refer will only run if connected to shore power or running the genny. Does this make any sense, or is this a wiring issue? Would an 1800w inverter be large enough to handle the refer load? The inverter is definitely working, as he can watch tv and power the sat receiver off the batteries, however, we were unable to find any hot outlets when only in inverter operation. We were boondocking this past weekend, and he had to run the genny continuously, which kind of defeats the purpose of having quiet time. Unfortunately, I have very little experience with the late model gas coaches.

Doesn't take much of an inverter to run a fridge of any sort, but adding a couple more 6v golf cart batteries (connected in series for 12v) would sure help on longevity. If you can't find an inverter outlet back there and when all else fails, find a convenient inverter circuit to tap off of and run to an outlet behind the fridge. Not much to that and I did so in a campground with an overnight stop one time, when our RV fridge refused to stay on gas. Once I got back home, I made up a auto relay circuit for switching back and forth on it's own, so no more on gas when going down the road and without even having to think about it.
