I have a class C, and you have more time than me but I'll give you my .02

1. It's awesome to take and be able to stop anywhere you want (I also think traveler / nomadic in you will like that more than most)
2. RV parks are some of the friendliest people in the world
3. It may say it sleeps 8 but its really only comfortable for 2
4. They're like a boat, something always need fixin
5. They tend to get used a few times then put up for long extended periods of time,


Overall they do give you a lot of flexibility in travel. See something you like, pull over and stay the night. I took my sabbatical and we drove from Seattle to West Yellowstone, up to the North East entrance, the Grand Tetons and ultimately Oklahoma.
