Batteries could be bad. How’s the water level?

Batteries could be good but need to be fully charged. You plugged in the camper to charge the batteries. For how long? Might be worthwhile to pull them and take them to an auto parts store that can load test them and deep charge them.

Are you running LED lights? Incandescent can be little power piggies. And the furnace blower pulls way more power than you’d think.

You could have a perfect storm of not fully charged batteries that are on the downside of their lifespan with low water and using more power than you would think…
