You're right that there are definitely some ridiculous travel days (they go from San Bernardino to Alto, NM on back to back days? It's over 800 miles so I hope their flight isn't canceled), but sometimes these tours are so bare bones that they do not travel with any crew whatsoever beyond a company manager, stage manager, and *maybe* a TD. All other crew (stagehands, wig/hair, makeup, day work, load-in/out) are picked up locally and become a documented expense that the theatres must cover, so at least they'll be well rested?
Tours like these will continue to happen as long as there are theatres that will pay for them, actors who agree to perform in them, and producers/production companies who are willing to try and make a quick buck at the expense of their performers' well being. On the flip side, you can say these tours allow smaller secondary or tertiary towns to bring in shows that they never would have otherwise been able to afford or present
