I would get your battery’s tested first if you haven’t as yet you may have a duff one pulling everything down.

both batterys only about 2 months old.

To eliminate a faulty battery, swap them over and the symptoms will change.
If the fault stays, then there could be some 12 Volt appliances connected to one of the batteries..
How does the alternator charge them? is it a 24 Volt alternator or 2 x 12 volt alternators, if this is the case could be a faulty diode in the alternator.
worth a try.
