Help designing a cover over my rear pumpkin

[jbice70gmc]

I’ve been racking my brain on how I should design the cover in my bed floor over the rear diff pumpkin that raises up above the bed floor when I let all the air out of my bags. I was just going to raise the bed floor 3” but am strongly reconsidering due to all the extra work. The pumpkin only comes up through the floor about 2”. I was thinking of making a square frame out of angle and then hinging a plate so that it could open and close. Not sure how I’m going to do it yet. My truck is bagged on a mini notch so the plate would lay flat at ride height. By the way I have a wood bed so I really don’t want a hump but rather something that would lay flat at ride height. I may still just raise the floor. Any ideas or suggestions would be greatly appreciated.
