We just got a 2017 2109S and there's a disconnect switch right at the battery. It's kind of like a key that you remove to turn it off. I'd be very surprised if the 2104S is different.
Yes it has a disconnect. We have a 2017 2104 and love it. As the last post said, it is a red key by the battery, attached to trailer below propane tanks. You can see it facing forward ( it faces camper on driver side).
