Need ideas for mounting a ladder on Packout

[Orion1876]

I am not familiar enough with the Packout stuff to know, can you slide anything underneath the bottom Packout box?

Can you ratchet strap it to the front securing on those corner supports/handles?

I guess I could ratchet strap it but I want something faster. I would prefer it to hang off some hooks and just bungee cord the bottom to prevent it from sliding around.

Another thought could be to attach a base or bin that the ladder would rest in towards the bottom of the rolling box.  Then put a couple hooks on the highest box to attach a bungee cord.  That should be pretty fast and easy.   Well as long as you can find a bungee that could hold the weight.   May need a couple bungee.
