[discussion] What would your solution be for long haul travel with animals?

To explain my question, and why I'm asking it:

I've had this debate in the past with someone who was anti-car but didn't really know why other than that it was popular in his social circle.

I'm distinctly curious what a solution for unusual travel habits would be without cars.

My situation is thus; I rather frequently do cross-country, round trips. Simple enough, right? Well, it gets more complicated than that. I show dogs. I need to take myself, potentially a friend or two, and on average 4 dogs several hundred miles, along with all the equipment.

For a fun experiment, this is the details of the show that I'm currently planning this month:

• 4 hours from my house by car
• 2 humans, 4 dogs
• 10 36" dog crates
• 1 36" folding grooming table
• Extra equipment that would fill a large suitcase, roughly speaking.
• two small containers of clothing
• cooler of dog food (frozen)
• vault of dog food (kibble)

I drive a Honda CRV for reference, 31mpg average.
