Dry camping is far different than walking in the door and flip the switch and pay the bill. If you use the RV as it's designed it's pretty much just an extension of flipping the switch but you just changed locations. Dry camping puts you in charge of your whole energy system. As Charlie said, now is the time to learn so you can look for important features on your next rig. The things to look for are battery storage size and height, distance between the batteries and converter,roof area for solar.
You can run with a digital volt meter to know your voltage at all times. Some people use a battery monitor which tells you the amp hours used and returned to the batteries. After using mine I'd never run without one no matter what battery type.
There are many ways to set your rig up and it's not one size fits all. If you dry camp a little or a lot you want to know your system so it runs smooth and you are comfortable.
