Lots of beer types don't travel well, which is partly why IPA was invented. As the story goes, those traveling from England to India needed to increase the alcohol content and the bittering hops for the beer to survive the voyage.
In any case it takes almost 24 hours for beer to settle after being moved as the shakeup foams up the beer (CO2 trying to escape). Whenever I buy a keg I always let it set in the tapper for a full day before access.
On the other hand, bottled beer seems to do all right in my on-board cooler since its on ice and I sandwich glass bottles in between plastic water bottles and haven't lost one yet. Yet.
Just make sure you have your home brew Federal Permit with you so you don't get accused of bootlegging.
Sometimes my mind wanders. Other times it goes away completely.
