I've had mine in for 2-1/2 years and it's never fallen down once. When you drill the sides to bolt it together you don't want to make it the width of the bed, you want to make it like 1/4" wider than the bed. It makes it a PITA to fit it down between the rails because you can't just slide it straight down since it's now wider than the rails. You have to slide it in from an angle while folded in the closed position so the sides can bend slightly and twist it in just right, but once it's in, the spring pressure from it being "clamped" in place from the outward force holds it in perfectly.
I read review of it falling in before I bought mine so I set the width a little wider like that and it's worked perfectly. What I was going to do if that didn't work was just drill a hole in each rail and stick a pin down through it so it wouldn't be able to fall off either, but I never had to get to that point.
Love the functionality of it, plenty of times over the years I've had to fold it up to fit more crap in the bed in a crunch.
Sorry to say this Reptar, because I really like some of your informative posts, but as an admitted "street queen" your opinion about the BakBox really doesn't support it's offroad capabilities. After my first offroad event with a BakBox in my truck bed, I could never endorse it for any other purpose than daily driver duty. As designed, it will provide the average F150 owner plenty of storage and versatility, but will disappoint even the casual offroader.
