Well I went for it!!!! Got the whispbar with direct mount kit and the Inno Low Down Cruiser Box. At the shop where I got the box it became clear why many may have not purchased this box. The back of the box extended over the rear too far to allow the end-gate to open completely. There was room for the box to sit a few inches forward, but the slots in the bottom of the box that mounting hardware use to attach to the bars prevented it from moving forward. So to make it work it required altering the box and voiding the warranty. I considered some other boxes, but none were as low profile so I decided to take my chances and alter the box to make it work. Here it is on the Jeep....I am very happy with it and it fits in the garage
!!!! With the crossbars and the box it looks like it sits about 12' from the chrome side rails to the highest point on the box. I have about 1/5" of clearance in my garage at a normal ride height.
