Diamondback Cross Bin Question

I am looking into diamondback SE cover. I was looking into the cross bin options and see the cross bin 8 and cross bin 4T.

Anyone use these? The cross bin 8 seems to be what I see most. Any issues with fitting things/boxes under the bin? How much does the 8 leave between the bin and the bed floor?

Seems the 4T would allow for more space in the bed under the bin and still use some of the “wasted” space above the wheel wells.

Thoughts?

 

Well I answered this question on my own in case anyone was interested. Just over 14 inch clearance Under the 4T cross bin. Overall I am happy with Diamondback cover and the cross bin.

 

Interested in this too. Photos are nice to see and helpful

 

How wide is the center compartment? Could it fit a 45” rifle? Also do you know the weight of this item? Thanks!!
