Compensating for GM crowned bed

I didn't discover this anomaly until about a year in when I noticed denting occurring in the front of the bed and on the camper where it meets the end of the bed. A result from the rocking motion from the built in see saw. Also noticed the distance from the bed rails to the camper was not uniform from front to back. Gap was less at rear.







So I made a wedge using 3 pieces of 3/16" wood sheets glued together. So its 9/16" on thick end and 3/16" at the thin end. Its 50" wide and 21" long. Then I slip that under the rear of my Dee Zee bed mat.



As you can see the mat leaves rubber on the wedge but little on the thin end leading me to think its too thick at 9/16" or too long.

So I wanna make another using 24" x 30" trucker mud flaps which will need trimmed.
MY QUESTIONS....
About how much drop is there on a 2016 Chevy short bed from the crown to the end of the bed?
Can I ignore putting anything on the other side of the crown?
