2017-2019 Superduty Factory Sprayed in Liner Drain Holes

Well, with debris, most can be plugged fairly easy. I blow mine out when washing the bed. Don't often park under trees so might explain why mine (two different years) don't plug.

We didn’t have that problem with 2010s. :)

That would explain some of it. Those slots are pretty narrow and all it took to stop all 8(?) of them up was some pine pollen and a few River Birch leaves. I took an exacto knife and cut some of the liner away to open them up some, but they are still very narrow.

I have a 2017 and mine are not stopped up or plugged. Maybe they sprayed yours on a Friday :D

My bed was factory sprayed. All holes are not blocked at all. Maybe yours was done aftermarket.
