I just made a new set of bunks using “Caliber Bunk Wrap Kit (23050) Gray 16′ x 2″ x 4″ w/End Caps”
Here is a link to amazon:

They took some time to install, but the results looked like all the pictures.
I used some additional ratchet clamps to hold the covers in place while I stapled the covers down with stainless steel staples. After the covers were stapled in place, I used the stainless screws provided to secure the covers.
The plastic covers make the loading and unloading much easier, worth the effort.
