We just got back from a weekend trip and realized that our growing family may need more than the Model S can provide. What I'm talking about is interior space, and space for dogs, in particular. We have two dogs (one about 45 lbs, the other about 20 lbs) are in the process of rescuing a third (about 40 lbs). The two existing dogs travel fine in our P85D, but when we have luggage, as we did on this weekend trip, there really isn't much room left. A third dog in a crate in the back seat just won't fit. Has anyone tried out alternative dog transport methods (I'm not talking about National Lampoon Vacation type....)?
