I have two 12volt in my 2008 3400RL Kirkland brand from Costco. They have never been pulled out. My fifth wheel is plugged in year around.

They are 6*1/2 years old ,and still going strong. On a recent hunting trip they were used every night to run the lights ,and furnace. Furnace ran off, and on all nigh for four nights. They never showed under 3/4 charge on the gauge. Charged them back up everyday with a small generator.

Winters are pretty cold here in Utah, but never had a problem leaving in the fifth wheel. and the fifth wheel plugged in. I see no reason to EVER remove them, I do check the fluid level periodically .

I am surprised, why bother to pull them out, if you can just keep them plugged in.

But to answer the op's question keep them hooked together, and keep on a trickle charger.
