Thanks for posting up this project along with all the pics!!!
I definately like the way you have it hinged in the middle for easy access to either end of bed if necessary.
It didn't look like it was supported in the middle of the frame sections. I think that would be my only concern.
So I wonder how much play/vertical movement you will get with the "draper canvas" once you get to speed??? I would think too much movement with the cover material would possibly lead to a tear or rip in the future.
