We have contemplated full timing a few times, but, nothing trumps the room of a big house (or 3), shop, barn and room to do anything you want (all paid for). We are retired so we can keep all that and travel as we see fit. I'm better than DW, but being confined to an RV, no matter what size, without our shops, barns, and all the "stuff" we have in all of our "buildings", and the things we can do with all of them, would be unbearable.
For us, it is unimaginable to set ourselves in an RV park, or even on 100 acres, and live in 400 sq. ft. JMO YMMV
