Bill,

With no load they should last more than a couple of days.

Last week I turned off my breaker and disconnected shore power from the coach so I could cut the grass between the coach and the house. When finished I plugged back in and went about my business. Four days later I went out to the coach and even though the AC was sent at 75 the thermostats were reading 79. I started fiddling around and turned on the inverter and my batteries were reading 11.2 volts. I fired up the generator and started doing some additional checking and low and behold, I forgot to turn the breaker on after I plugged the coach back into its shore power receptacle.

I only have 2 6 volt batteries and only dropped to 11.2 Volts in 4 days. With 4 batteries you should be lasting longer than a couple of days especially with the house batteries in store mode.
