RV Batteries

Kind of a dumb question.  I got lazy & didn't remove my trailer batteries which are wired parallel.  I have been plugging the trailer in for a few days then unplugging for a couple days.  Is this adequate for charging in CO cold?  I was going to throw a trickle charger on there but I am not clear if one trickle charger will take care of both batteries since they are wired or if I need to throw two chargers on there but then wouldn't I need to disconnect the batteries from each other since they are wired in parallel?

Since wired together, they are technically one large battery. So,  single charger will work. Now, if they depleted, a small (low output) "trickle" charger will struggle to supply enough juice to recharge them. if they just need maintained for storage, a low output charger will work to keep them full. If you have or get, a multi-stage smart charger, you can just leave it connected and plugged in. I would not suggest this with an old school "trickle" that just supplies a low but constant charge.
