Hello.I have a throw in bed liner and like it as I can throw stuff in bed without. Having to worry about denting bed.however the liner goes over the bed rails and they don't lay flat in hot weather.has anyone cut the rails off a liner and put on aftermarket bed rail caps?

 

I've never seen anyone cut the sides off. If you prefer this type of liner, you could buy a new one that goes under the rails and then put an aftermarket rail cap on the truck. I prefer a spray on liner since it doesn't chew up the paint under the liner like the plastic ones do.
