Bed liner for my new GMC, what to get.......

LineX seems to be the best overall.

Spray-on's are far superior to the slide-in's. No dirt and rocks under it to scour the bed paint, and very easy to hose out. I've had a spray-on in my last 3 trucks and don't have near the problems my daughter has with her slide in. We used to farm so the trucks did and still do get hard, rough use. I usually drop the truck off at my local detailer for the bed liner on the way home from picking it up at my dealer.

My Ram has a spray in liner and I think it's the way to go. It's grippier than the painted steel and it's held up well so far. Plastic liners can trap moisture under them and the ones I've been around are really slick so cargo can slide around on them.

I'd take it. Spray ins are nice.
