Just picked up our new 261BH. Love it so far! Took it camping straight from the dealership. That said, it's in the driveway now, and when parked I always leave my fridge/freezers open. It's not on shore power, and I flipped the battery disconnect, but I noticed the light in the fridge is still on. Is that normal? How do others keep the light off while venting the fridge? And why wouldn't the disconnect kill power to it?
