I have my TT in a nice boat and RV storage facility in the California Delta, with individual locked garages. Trouble is, it is below sea level and the levee is 1/4 mile away, so the County wouldn't let them put electricity in the storage units.
I solved the problem with a 15 watt solar Battery Minder system. It is all you need to keep your batteries topped off. Last week I was experimenting with running the fridge on 12 volt, and ran 14 amps out of the battery. Within 3 days, the battery was back to 100% per the battery monitor. The Battery Minder is a smart charger and the amps and volts drop to a maintenance level as the battery reaches 100% charge. I am very happy with its performance.
They are available through Northern Tool for $145:
