I have a Jeep and I do not have the front and back cross bars on my rack. I used all 4 straps, out of paranoia, 2 straight across and two diagonal front to back on the carrier. I didn't ride more than 70MPH (yet), and the bag didn't budge. I also did not here any noise, only a little louder wind resistance than normal. This is a cool way for me to move my must haves to a new state!
