How to make money while living in an RV full time

I've been trying to figure out how to earn a living if I decided to go rving full time. 

1. Well my etsy shop is doing well, I think it can support at least my fuel (gas) :) I'm averaging about $400 and over per month.
2. My google adsense is becoming more and more predictable. (over $200 per month) that should cover insurance right?
3. I do operate an online bookstore.  
4. and maybe I could set up and sell my crochet stuff on route.

anyway just thinking out loud.
