I did a little google fu on 4-runners and it looks like you'd be hard pressed to fit a pair of 300 keenels in the back with the rear seats up. I'd imagine the same would hold for most mid size suv's.

If you go with a truck with a bed and you have a truck that the rear window rolls down, you have a heated bed. There are also auxiliary heater options that would be worth considering.

I'm thinking the double cab tacoma short bed with a shell might be worth considering.

Having had both a 4-runner and an extra cab truck, I found the storage in the 4 runner underwhelming at best. With a truck it's nice having a bed to transport items that are dirty or apt to spill, as it's the bed of a truck vs. the interior of a car.

Now if you really want to spoil your wife (and I haven't found dimensions to verify that a pair of kennels will fit but my gut says they will) I highly recommend the ultimate family non mini van car.
