Not long ago my family was travelling western Kentucky on a four lane highway. I was driving. Up ahead in the distance I saw something large and black in the edge of the right lane. As we drew closer, it became clear what the thing was. It was a drop in bed liner that had gone flying from someone's truck.

Here's the problem. Drop in bedliners must fit very well. If they don't you get wind under the liner. When that happens, the liner starts moving and vibrating. Than several things can result.
The liner can begin to crack at the hold-down bolts. Over time the cracks spread and the liner gets even looser. It could eventually go sailing away like the one I saw. Here's another problem.
A vibrating liner can also wear away at the truck bed paint. If the paint is worn away, that's a place for rust to start. Since it's underneath the liner, you may not notice until it's too late.
That's why you want a really good fitting drop in liner. You don't want a liner that's moving with the wind.
Get one that fits right and you can't find a tougher and more durable bed lining. A thick drop in bed liner will stand almost any kind of hauling abuse.
