Extang Solid Folding?
I had the Solid Fold by Extang for 6 years on my F250. You will not be able to use the auto tailgate release because of the way it's designed. Everytime I closed the tailgate, I needed to lift up on the tonneau so it wouldn't tear the weatherstripping at the end. It's a very snug fit. Great tonneau, but not without it's flaws.
