Mounting stuff to your cap ceiling?

Has anyone ever mounted anything to the ceiling of theirtruck cap using the bolts protruding from the bottom of a rack track?

Although it’s a completely unnecessary, I really feel like Igotta mount something to these dang bolts. I’m thinking about putting some longer bolts in there, so they protrude farther,then mounting a few brackets to hold a couple of rotopax (First Aid and emptystorage pack). I figure the entire thingwould weigh about 20 – 25 lbs, assuming the empty storage pack was full oflight stuff. Any reason why this wouldbe a ridiculous/bad thing to do?

Here are some concept diagrams I tossed together onpowerpoint.

 

I put a Eureka tent gear loft in mine for when I am camping and sleeping in the truck. Im wondering if a couple of quick fists could be mounted there to as a rod holder.
