I like the idea. You are right, I do read all your sites anyway, so it makes it easier if they are under one roof. I like what Hawt mentioned about rankings. You might want to keep that in mind. It is harder to get more readers if they don't know the purpose of your blog. Simply living awesome is a hard one to pin down. But, it worked for here so it most likely would work somewhere else.
I do like the idea of mixed posts. I look forward to longer ones, but I would read the shorter ones too. I like the idea of regular posting, but I hope it doesn't make you stressed to post. A forced post isn't a good post.
The idea of short books/guides is nice. It would be great to go more in depth with some of the topics you discussed. I don't know if I would be able to buy them, but it would help people that really do want to live in their RV, earn a living without a job, etc.
