I had a Fold-a-Cover G4 tonneau on my '14 Silverado. HAD. I now have a topper.

Likes - Solid construction, good locking and latch mechanism, good esthetics, access to the front section w/ front latch and back 3 sections w/ rear latch (this is fold-a-cover's claim to fame)

Dislikes - Cost (one of the more expensive folding options), Difficult to remove (must unbolt) if you need access to the entire bed/want to remove the tonneau.

Ultimately I got rid of the tonneau and went w/ an ARE Z-series topper which is what I should have bought in the first place. In the end I found that not much stuff could really fit under the tonneau and often when I wanted to protect something from the elements it would not fit under the tonneau. I am very happy w/ the topper and should have gone this route to begin with.

My biggest advice would be to go w/ a tonneau that can be easily removed (as in without tools) if you need access to the whole bed. Also don't be surprised if a lot of cargo does not fit under the tonneau and it needs to be removed, exposing the cargo to the elements/theft/etc.

Good luck!
