Hello, I haven't taken the freedom invoking move of getting a RV yet but am in that first steps area. I am 29 and my gf is 30, we are both at a stage in life were we don't have a lot tying us down....
I have to agree with ParrotHead Mike. I wouldn't lock yourself into one type just yet. I would start by checking out a few different styles and find what is going to best work for you. You may find that you can go either way if you get the right combo of features. You may find more used Class C depending on your locale.
