Does anyone travel with a dog in a crate in their ELEMENT? I have a Vari Kennel which my boxer travels in for safety reasons, otherwise, she'd prefer to be on a seat as well. How do the crates fit? Do the rear seats have to be moved or would the crate fit sideways in the back? I noticed that there are no side mounted speakers nor subwoofer in the floor in the cargo area which is ideal for animal ear drums. I, however, enjoy my music loud.
