Hey buswarrior, we'll be charging the battery through shore power, when available, otherwise it will be solar, and the monster 50DN alternator when driving or idling. We dont plan to be "disconnected" for long period of time. We may stop, and spend a night at a rest stop from time to time, but it will be mostly going between state parks, and rv campgrounds. We plan to have around 20kW available, which should give us a good night's rest with a/c on full blast.
