12 volt system

[Eric27]

My first time dry camping in our 2018 Windsport 29m. The 12v system keeps shutting down and restarting. Sometimes it takes a second, other times it takes 10 seconds. Any thoughts?

Sounds like a thermal overload tripping. What are you running off the DC buss? Any inverters involved?

It would not be the first time a "new" set of batteries were bad out of the chute. When you have access to shore power do the batteries fully charge normally to 12.6+ volts when coach loads are off?

Thanks,
Yes they charge right up. I think I will get a hydrometer and check them

I suspect that you are having too much electrical draw for the amount of battery storage you have, and voltages are dropping down to the point that the system is shutting down momentarily to protect it's self..may be time to "battery up" with additional batteries.
