Exactly. If you wanted to sell your truck, it would be worth less because of the drop in liner. It is a liability. If you had a spray on liner, your truck bed would be protected and would be worth more than a truck without a liner. Drilling any holes will invite rust and ruin your truck. I would say for now, remove the liner. If the liner doesn't protect the bed, what good is it. Take it out and save yourself the grief.
