If equipped with a 2000w Xantrex inverter, check the circuit breakers on it. The lower breaker on ours will trip with too much load without tripping any breakers in the circuit breaker panel. When tripped it will take AC power out to the, front TV, 110 power at the dash, entertainment cabinet, 2 kitchen outlets, microwave, front GFI outlet, and bath GFI. In other words almost everything on the passenger side of the RV. All 12v, roof systems, furnaces, refrigerator, water heater, bedroom entertainment center and washer/dryer still work. Only the lower breaker on the inverter has ever tripped, don't even know what is controlled by the upper breaker.
