New to the TT world

I didn't know RV manufacturers were selling upgraded power systems with claims of running air conditioner. Someone chimed in that the 400 ah LiPO4 battery system with 3000 watt inverter/charger and 570 watt solar were typical of mfg-supplied junk, but based on the numbers that is absolutely not true. That is a very nice sounding dry camping setup, although I can't vouch for the quality of the components. But as has been mentioned repeatedly, not enough to run your air conditioner for a usable duration. Even your caveat of only a couple hours of day will take most of your battery capacity, leaving you short on battery to operate the rest of the camper when boondocking. And then you start the next day at super low SOC on the battery with little likelihood of your solar getting enough harvest to get you up to >90% again.
