Welcome to The Forum.
It seems to me the OP might be looking to get into RV'ing/camping for all the wrong reasons. It's not like the videos you see from Go RV'ing commercials all the time. As others have pointed it, there can be a ton of maintenance and expense to owning most size campers. Campground costs are going up, and they may or may not be cheap, depending on the amenities required.
If the OP has sloppish tendencies, there is less protection from being evicted than most states have for apartment dwellers.
Should the OP still decide to give the RV route a try, research, touch, and feel will be his/her best friend. Scour the internet for articles and information on different RV types and what each offers. Check out YouTube, there are many, many excellent RV videos there, and don't forget to check out some RV traveler videos while there to see some of the trials and tribulations involved with RV'ing.
One thing I wouldn't suggest is renting an RV. It is extremely expensive, renting a small Class C to park in your driveway for a weekend would tell you zero about RV life, and cost you over $500. A recent statistic came out that 44% of new RV owners will change from their initial RV purchase to another more suitable model that will fit their needs better within 2 years. Why? Because now they have gained experience and knowledge of what they want, and what they can do without. Renting for a weekend or even two weeks would be no more than going on a Caribbean Cruise, and think when you come home, you'll want to buy a cruise ship.
