I have 2 G29 batteries & removed them for the winter. Since it looks like we won't be doing any extended dry camping I'm only going to install one of the batteries this spring. I figure even if we do one dry overnight I should be OK.
For sure, one Grp 29 will get you through one night.
A more efficient way might be to use both batteries since you will draw down two to a greater SOC. That should result in more charge cycles (longevity) than using one and leaving one in storage. There is also the theory of using one and leaving one floating so that, in the future, you have a fully usable replacement. An alternative, also, is replacing both with GC2 6V batteries and using a disconnect switch. The storage life of a GC2 6V pair is pretty high. Only the most abused and ill treated 6V batteries will not survive a long Winter. That alternative means no battery carrying is necessary. You could also rig up a small solar panel to have the ultimate "hands free" setup.
The reason I suggest the "hands free" alternative is that I always have hated carrying batteries. That attitude is not diminishing. I've probably schlepped more batteries than the average guy from my work experience. You get to know what works and hope it doesn't involve me too much, lol.
FWIW, I have 5 batteries at present in my system, split into two banks. All of them are being maintained by a solar panel. Solar, with a good programmable controller, does a better job than I can with multiple 120V chargers.
