The newer 190s - after 2010 have two 6 volt AGM coach batteries - about 220 amp hours. Older 190's also had two coach batteries - I don't know if this was an option in 2004. I have an DC/AC condenser fridge and I have no problem leaving my fridge on DC with my two AGMs while the Roadtrek is parked for the day. I have not tested how long it can go without being driven or plugged in - or running the generator to charge the batteries back up but it has gone past 12 hours as it is. The three way absorption fridge may draw more power and drain the batteries faster. To figure out what you can run and for how long you need to determine how many amps you will draw and then see what that means with the number of amp hours you will gain by adding the second battery.
