Quick Question solar plug

Don't know about the Zamp socket.  There are at least a couple of theories on keeping the pod plugged into shore power while in storage.  I opt for doing it and it seems to work fine after two years.  There is a built in battery maintainer that works while on shore power.  That's all you need.  You should still check the water in the battery from time to time.  The other theory is to disconnect the battery, maybe remove it, and put it on a charger for about 24 hours a month.  That seems to me a good plan if your pod is stored remotely without access to shore power.

I think the Zamp socket is mainly for solar to recharge batteries while camping, but I'm sure there are other ways to take advantage of it.

You want to keep the pod in the garage with the running lights on??  That's a new one to me.  (Why?) You'd have to run 12v in through the bargman connector, as far as I know.  Zamp or shore power won't help directly, other than to counteract a significant drain on the battery.

Search Amazon for SAE connector.  You can also get battery minder cables at auto parts stores.
