battery voltage on new Miramar

[donw]

I just purchased a 2019 Miramar 35.2 on Saturday 5-17-2019. I drove home and it is sitting in front of my house. I noticed the battery monitor has gone from 12.8 to 12v so I flipped off the battery power. I checked the power the next day and it is 11.5v. is this normal and how low is it ok to go down to? Also would this take a lot longer to go down if I installed 2 more 6v batteries and that raises another question. The two house batteries are 6v deep cycle I think Trojan and do I have to add like or can I ad two 6v deep cycle Interstate golf cart batteries from Costco?

Thanks,
Don

Don you might want to move this to the Class A Form section.

Is your inverter on? Is your USE/STORE switch in STORE? Even with the switch in STORE and the inverter off you will still have some parasitic loads but if your batteries are good (which may not be the case after sitting on the dealers lot) you should stay above 12.0 volts for a week. At 11.5 volts your batteries are over-discharged and damage is occurring until you get them charged.

Charge them, test them, then worry about adding more.
