I just installed this in my 2022 P4X and if anyone is considering a bed liner, I definitely recommend this one.It arrived well packaged, wrapped in plastic in a cardboard box. That was a good thing since the courier apparently tried to destroy the box but the liner was 100% ok. Shipping was ridiculously fast too, I ordered it on Monday morning and it arrived on Wednesday afternoon. Considering this was shipped out of the US and I'm in Canada, that's impressive.It comes folded in the box but after laying it out flat for a day or so you can barely even tell it was ever folded. Mine still has a small amount of distortion in the center but I'm sure that will flatten out over the next few days as the material relaxes, it's barely been out of the box for 24hrs right now and it's not very warm here.Installation was a non-event. I spent 5 or 10 minutes cleaning out the bed to ensure I didn't trap any debris under it and then it just dropped into place with no effort.I'm really impressed with the fit. The ridges are perfectly designed to nest into the corresponding ridges in the truck and sits very nicely in the bed. It's well contoured at all the corners etc, comes up the wall about 1.5in and even captures the small lip at the rear of the box. It has lines molded across the width of it that nest into the truck and I think that, along all the other molded details should prevent it from moving around, even with the tailgate down. It doesn't interfere with the drain lines from my tonneau cover and I noticed that it's made with a rolled lip that should prevent the edges from curling in or losing their shape over time, that's a nice touch.The material (TPE) is nicely molded and seems pretty durable, TPE's are typically oil/acid resistant so that's a bonus when carrying gas cans, oil jugs, greasy parts etc. And when it came out of the packaging there was none of the chemical stink that's so common with many plastics.People have already been asking why I would put something like this in my truck since I have the spray-in liner and for me, there's a few reasons. Putting skis in on the spray-in liner is like sliding them across sandpaper and it's really hard on the them so this will protect my toys in that way, with a tonneau cover on it's really annoying when boxes and stuff slide forward and this should help to keep things in place nicely, and anything I spill back there will be much easier to clean up.I'd give this a solid 5/5.
