Welcome to the forum. Would agree with renting first to get a better feel for RVing. While there is much to do and enjoy, you also need to take care of tasks that do not need to be done with a house or apartment. For example, when you pull into any campground and get positioned, you will need to level the RV. Not a big deal, but needs to be done. Further, you need to be comfortable with dumping your black and gray tanks, again not usually a big deal, but needs to be done periodically, and can be quite smelly and some times messy. If you don't have any electrical knowledge, you will need to learn a few electrical basics. All in all, no real big issues. You just need to learn about how to handle them, because it is different than you will find in a house. If you rent an RV for a time, you can learn on someone else's RV, and apply the lessons learned to one you may purchase down the road. Finally, before writing a check or heading to a dealership, take some time to learn about the various types of RVs including pros and cons of each. A good way to do this is to visit a large RV show with many types of RVs and manufacturers. The largest show in the country is in Hershey PA in mid-Sept. When you go to a show this big, plan on a few days to see the rigs and attend some seminars.
Best wishes for success.
