If you have a bedliner, you have to pull that load in tension across the back and tighten it with motorcycle straps or the like. If not, it will slip right on out the back, friction free. Kind of one of the points of having a bedliner. A poseur truck owner wouldn’t know this, the same as they wouldn’t know how or why to tie a trucker’s hitch. You don’t have to be completely inexperienced to screw this up but it helps.
Very good points.
I had started to describe with more detail that I was a cabinet and furniture maker for decades and still work in industry as a designer, but was annoying even myself with the description (didn’t want to be lecturing folks further). Anyhow, I once saw a guy I worked for send a client off with an expensive piece I had just finished, without lifting a finger to secure the load. That piece exploded out of the bed, somewhere between our shop and the Bay Bridge, splintering onto the freeway. Dude made this woman pay for replacement, said contract stipulated as such. Even supposedly experienced jagoffs like that guy can blow it royally.
