When I bought my truck new I got a drop in bedliner. Did not take to long to learn that drop-in bed liners and slide in campers do not work well together. I didn't know a camper could move around that much and stay in the truck!
So I removed the drop-in liner and replaced it with a rubber bed mat. Have had not problem with the camper moving since.
But I still wanted the drop-in liner to protect the wheel wells from the camper when loading.
After some thought and work with a saw, I cut the bottom out of the drop-in liner. Installed the remaining sides in the truck, and put the rubber bed mat where the bottom of the liner was. So far so good.
