Cold cranking amps (CCA) are of absolutely no benefit in deep cycle rv application, the battery will have a much shorter lifespan due deep discharging, you want the most amp hours (AH) possible. If using a deep cycle battery in your boat to also start the motor you'll need CCA or for starting your vehicle, but not in a RV. This is the reason so many use 6 volt golf cart batteries, they're designed to be charged/discharged regularly
My point is that cold severely hampers a battery's ability to produce power, especially lead acid type. Discharge of a battery causes sulfation which shortens life. Also possibility for freezing if battery drops too low on charge. The CCA analogy served my purpose to illustrate these points. Deep cycle have the same problems.

I totally agree!
My comment was more to inform others that the same battery in their vehicle referencing CCA is NOT going to work very long in a RV, cold or otherwise.
I am thinking of doing the same thing. Just leave connected in trailer and connect to shore power to charge every 3 weeks or so. I am in southern Ontario and have two 12V batteries connected in parallel.
