Our RV, shown in signature, has an on/off switch for the battery. Like you, we were overloaded with info during the PDI...remembered very little. We camped 5 miles from home first....good thing. We didn't realize about the on/off switch until we went to use it and the battery was dead dead dead! We took the battery home, bought a charger and it took a long time to recharge it, it was discharging?? Anyway, I suspect there was some damage, but we've been fine now and are constantly reminding each other to shut it off when stored.
As for running things at our house. We don't run the AC, it just kept tripping the breaker. We thought we had used the right extension cord and adapter, but the AC tripped it anyway. We run the frig, that's about all. Our frig cools off in just a few hours, then we can just run it on gas once we take off. Our driveway is very level, so no worries for the frig.
Enjoy your KZ...we love ours, just want a bigger one now! (of course) I envy folks who get it right the first time.
