Here's goes nothing - my first rv discussion...

It's a fun idea to consider. Maybe you could rent an RV for the next couple of shows and test it out a little. Stay in an RV park, commute to shows, deal with a tow vehicle set-up, dump your tanks, live in a smaller space with all your business stuff and see if it works, or how you could make it work.

I think my biggest concern would be the dream of working on the road full time and trusting the business to run from afar as it does when you are there.
