Craft Business while RVing

Another option, in addition to your traveling, is longer term stays at specific RV parks inhabited by snowbirds. You could contact parks in areas you'd like to spend 2 weeks to months to find out if you could trade teaching classes for free or reduced cost camping. Sounds like you have a good variety of crafts that easily transfer to craft classes. That still wouldn't prohibit you from doing shows in those areas on weekends.

Another thought on RVs is that you can take an RV and redesign the interior to fit your needs. Removing a sofa or dinette might create usable craft space/storage.
