Welcome from a fellow Hoosier. We are in Salem, where are you?
We started out tent camping several years ago. Some of our fondest memories are from tent camping. Now, four RVs later, we have a fifth wheel. When we were tent camping, we never thought a big RV would be in our future, but look what happened! You may be started down the same road.
You might want to try an overnight in the pop-up in your driveway or if you have a campground about 30 minutes from home, you can do that too. That way you can try all the systems and if you need something you won't be far from civilization. As you use the camper and run across something you don't understand or something you need, write it down. You can post questions here and should get some great advice.
If you need supplies and equipment, you can shop the RV stores like Camping World but actually they can be a bit pricey. Walmart has a good RV section and you can find a lot of other things in the home and kitchen areas. Also, Amazon is a great resource.
Good luck and remember that there are no camper police so have a good time.
