Tom, if you haven't found
Escapees forum yet, go over and introduce yourself there. Probably the largest number of fulltimers are on Escapees, since the company was founded to take care of fulltime RVers by fulltime RVers.
Have you figured out what you will do about mail, voting, DL, vehicle registration, etc. I'm assuming you will want to 'move' to a tax friendlier state - SD, FL, & TX all are RV friendly and no state income tax.
Follow the 2-2-2 plan - 200 miles per day, in a park by 2:00 pm, stay at least 2 days. That way you are rested when you drive, you are off the road before any 'rush' hour and will be able to relax while everyone else is trying to get into the last few small spots, and you will get a chance to maybe visit some local places of interests.
As said, anywhere south of I-10 is good for the winter. We enjoy the desert, so we are here from October to April.
