Hey! I've been asking this forever, and now I have the car.
I have a 83 lbs. White Swiss Shepherd, 25" whithers and 40" nose to base of tail. She fits. It's not as much head space as my Subaru Outback, but she can stand up and turn just fine. When standing up, her head isn't obviously fully up, she has to stoop to look, but she can stick her head over the back seat and be very relaxed.
Dogs probably shouldn't be standing up all that much in the car anyway.
I'd say the footprint of the cargo area is probably as much, if not more than the RAV4. But the angled hatch is where you're going to miss the headspace.
I'll post photos in a bit.
