Keeping Batteries Charged
I have two new Crown CR-240 6 volt deep cycle batteries. They were installed this past spring as part of my slow but ongoing solar addition to my 5ver. I don't want to ruin them by letting them drain ...

Yes, get a battery switch to stop any draws during storage, use it whenever you are disconnected from power.
A fully charged battery will not freeze. most should be charged about once a month to be safe.
The OPs battery has a self discharge rate of 3.5%/week at 80F which is excellent. Still my calculations show that it will self discharge to 50% SOC in 19 weeks at 80F, less I assume in lower temperatures. This will shorten battery life.
I would want a temperature compensated charger that maintains the battery per the Crown specification.
