So i came to find out that I had a similar issue with the quickfist clamps. I hit a lumpy sugar cane field doing about 50. After about a mile, The quickfist on my 5 lb extinguisher, my shovel and my axe, all gave up. My flashlight was hanging on by a thread.
I decided to buy another quick release mount for my 5 lber ( using a bleepin jeep steel extinguisher mount)
I also bought an axe/shovel mount for a warrior roof rack.
I haven't installed the replacement mounts yet, but the quickfist clamps don't seem like they'll hold up when it gets sporty.
For my pro eagle jack, I welded up a mount that is attached to the bar I made that serves as the center mount loop for the bed mounted spare's tie down.
I still have to figure out what to do with my flashlight and trucker's friend tool. The quick fist clamps have held up for the trucker's friend so far, but now I don't really trust them.
I'd prefer to not end up with projectiles with sharp edges that weigh 1-2 lbs flying around when i least expect it though.

Have you checked out built right industries bed mounts? I have my shovel and axe mounted.

we mostly all already have them. The quick fist clamps that they recommend dont seem to be up to the task of keeping thinks secure when you drive at speed through whoops or jump the truck.
On a side note, to be clear, i busted the quick fist clamps even with left foot braking and smoothing the truck out to the best of my ability.
They would have snapped within 5 minutes if i was a hammer down "send it always" kind of driver.
I do have deavers and bumps too, so it isnt like i was bottoming out hard.
I've taken a look at a few race prepped trucks. Seems to me, most of those folks are using drake mounts for the extinguishers and simple metal hose clamps to hold everything else in place.
