Hi All, Just wanted to comment on this: " However, I have decided on the new (2004) Toyota Sienna mini-van. The passenger windows do go down, the AC is in the back, AWD is available. It is wider than most vans so could fit 2 crates side by side and still have the back seat or fold down the back seat to put another crate in. It also has good ratings (as most Toyotas do)."
I actually bought one of these for my three big dogs. As much as I hate mini-vans, this one works for dogs. If you want more info, let me know Liz Murray Calgary Alberta
