Good for you Denise! I've been full-time RVing for almost 5 years now and love it! We have a 40 foot class A diesel pusher. We also have 3 large dogs but still have plenty of room. Hahaha! No really! We don't have a house anymore so this is our only home. We have a mail service that we use as our permanent address for vehicle registration, voting, etc. When you make the commitment to do this, you find that there are so many material things that you can do without and still be comfortable.
I retired now, but we've met many RV people who still have a regular day job. Also, most of the campgrounds that we've been to hire people to do all sorts of thing around the campground in exchange for their site and sometimes for pay.
As for the type of RV it's all a matter of personal preference and lifestyle. Each has its advantages and disadvantages. Before you take the plunge do your research.
Don't forget that RVing is not camping. There will be many days that you'll appreciate those TVs!
