batteries draining overnite

[whitechief]

I have a 2019 Starcraft Autumn Ridge travel trailer that the batteries completely drain overnite.I've checked all fuses and everything seems all right.What would cause this to happen?

Is this parked for storage or are you boondocking when it happens? If it's for storage then make sure everything is shutdown I usually unhook my 12v power when not using camper for long periods, saves the battery. If boondocking then you need to check what amps your pulling and do the math to see if your battery is big enough to run everything for longer than overnight. The more stuff you run the shorter amount of time the battery will last. You might need to add more batteries. You also might try testing your battery because it might just be a bad battery.
