How to winterize batteries on the TT?
I have dual batteries for my TT. How should i care for them during winter? Also, if you plug in your TT does it keep your batteries charged or do I need to get a trickle down charger for each batter...

Thanks for all the tips, i think I'm going to leave them on the trailer and hook them up to a charger!
No need to put them on a charger for the winter provided you disconnect the batteries from the trailer.
As long as the batteries have been fully charged, and disconnected from anything that can drain the charge (like a RV), they can be left alone for 3-6 months without needing to be charged.
If you really want to use an external charger, be aware that most portable "smart" chargers will shut off and never turn back on once the charge cycle you started ends..
Older non smart chargers can and will be worse at boiling the battery than your RVs built in converter charger since they do not reduce the voltage and keep on with the same voltage.
In some respect as long as your RV has a three stage charging converter (most have since the early 2000s) your battery will be fine left alone with being plugged into the shore power.
Your choice..
