Camper shell gets loose

'13 Tacoma 4x4 DCLB TRD Sport
I installed kv voodoo bed rails and recently installed a hard top. I am using brackets like the ones on the best top.

The issue I am having is while off roading. Washboard roads and bed flex while crawling keep loosening the brackets and the camper will slide. I have been lucky and have not lost the camper but I can't keep it on without making sure this will be tight. Headed out next weekend and I need to have the camper ready for sleeping in the snow. What other means have you used on your rig to keep your camper german specced, gutentight?

EDIT: The threads are not backing out they will vibrate all the way until they fall out of the bed rails.

TIA for the input.

 

Try a little lock tight blue threadlocker

 

Tried that already. I thought they were backing out and then falling out. But the threads are not backing out. They will vibrate all the way until they fall out of the bed rails.

 

You're saying they vibrate/slide all the way to the end of the rails and then pop out?

If so then you probably need to to tighten them more

 

Put a lock, clip or pin in your rails so they can't walk out.
