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.
ALL of which is overkill for those of us including the OP who rarely camp without shore power. The better solution - K.I.S.S. ... one battery, size of your choice from G24 to G31. :B If you're at all concerned about back up simply set up your truck to load support the trailer those times you may deem it necessary. For me, that's when we lose campsite shore power and I want to use my inverter to run our coffee machine and toaster. Since I'm powering the inverter with a single G27 voltage drop is excessive under heavy load but load supported with the truck idling it's a non-issue. If I were dry camping regularly I'd unquestionably run 2 G31s or 2 GC-2s but for occasional use load supporting with the truck is
much simpler. Pics are in my gallery
