As a new person entering into this in a limited capacity I think you are doing the right thing to get your feet wet. I would invite you to check out the two links at the bottom of this post where you can find a lot of answers and information you seek all in one place.
The first has a link at the top of it to "a Bug-Out Car". A car converted to take off and travel/camp in and live out of. Without too much conversion. And still be usable as a car for yourself.
The bottom is a portal of information & links to make planning your travels & living on the road more safe, comfortable, and convenient. Some of the trip planning software in the portal will allow you to take a virtual trip from your computer and see your route/itinerary just as though you were driving in your car.
All the best !
