I love that this crate has multiple doors.  I leave the garage door open when I'm at home with my puppy.  She has a secure place to go but I don't feel like she is "locked up".  When traveling it really doesn't matter which way the crate is put in the car, there is a door that is convenient to open.  My only suggestion would be to add tether rings that a seat belt could be strapped to in order to secure the crate for travel.  I'm not aware of this on any crate but it would be nice to have.
