Does anyone haul a truck camper with a DuraLiner in the bed?

I tried the plastic bed liner many years ago and got a lot of camper movement. But I did not have a rubber bed mat on top of the drop in plastic liner.

The other problem I found was in certain conditions, the drop in bed liner acted like a child's swimming pool and collected standing water. You don't want your camper bottom setting in standing water.

I ultimately got rid of it and got a sprayed in liner and rubber bed mat.
