Rotopax with rotopax mount

Hello everyone. I am new to the forum here. New to the Taco world.
I recently scored 3 two gallon rotopax (1 black storage, 1 fuel, 1 water) and had some questions for those that have them. Give. The dimensions 17 3/4 x 13 1/4 x 3 I was planning on standing all three across the back of the bed standing tall which given my measurements will put them at exactly the depth of what the bed is 17 3/4. Also fitting all 3 perfectly across the back. My main question is regarding the rotopax mount and how it allows them to be mounted. Can I mount either orientation or is it specific?

I am in the market for a tonneau cover specifically the diamondback and would like to know if I will have the clearance

I had a convo with @catastrofe regarding this and he gave me some fantastic insight, but any input from others that may have this setup would be appreciated.

If the rotopax mount does not allow full maximization of the sihe any other mounts you can recommend.

Thanks in advance.

Hahahaha!

I don't know for sure but from these images found using a quick google search it seems like they should fit with a diamondback. Unless one of the struts or inner ribs hangs too low. Also it seems you'd probably have to hang them horizontal opposed to vertical or go with the more square size.
