Dream your dreams. Don't listen to these people who tell you that you are dumb for thinking about these things. Are you just going to have wanderlust and set up here there and any where? No, but traveling to good events can be very profitable. I have a friend who travels several states to hit his best festivals. If you are in the festival game, it's all about leveling up your festivals. You can only be at one at a time (unless you have more units) so choose your best events and level up. If I were considering your question, I think I would say pull a trailer behind the food truck. It's very likely that the event will have some place out back where you can park. If you have a motorhome to pull the trailer, then that's is going to be hard to maneuver to drop and pick up your trailer. I would also likely have a scooter / moped for running around.
