I can teach you one or two things about boxed wine right now. When you live in an RV it doesn't roll around because it doesn't come in a round bottle. It doesn't break because it comes in a plastic bladder in a cardboard box instead of a glass bottle. If you care about fuel efficiency it is better to save weight by having plastic and cardboard instead of glass. Cardboard boxes stack nicely and save space in your overhead compartment compared to bottles. When you cork an opened wine bottle the air inside makes the wine go bad fairly quickly. With box wine, the bladder is flexible so no air goes into it. Which means that the wine remains good indefinitely even after it is opened. In spite of its reputation, box wine is actually pretty decent wine. And it is dead cheap. About $12 for the equivalent of ten bottles. You do the math.
