Be sure there is a way for everyone to know that you are just taking time out to recharge and not off by yourself in some sort of snit. When there is a meeting, make an agenda so all the topics can get covered. Informal communication patterns will work for some bands, but others need a very formal system of keeping the information flowing. Debrief the trip once you're back home. Review the good, bad, and ugly and see what new approaches can be identified.
Bands are typically very good at making time to see that all things musical are just so.
If an equal amount of time were taken to monitor the rest of the road trip process, there would be far fewer blowups.
