Living in an RV isn't exactly "camping" in my opinion. We've done both. REAL camping and living in an RV.
On vacation one year we camped (tenting) for almost 3 weeks. If you have the right set-up you can be quite comfortable but I have to admit I was more than ready for a hotel room by the end of that amount of time.
All that fresh air and sunshine and living in the outdoors ..... it's great!
