Check out the extang solid fold 2.0. It secures with just 4 clamps that happen to sit right above the top four tie down hooks of the bed (2 in front, 2 in the back). I purchased a pack of steel zip ties, ran two through the tie down hooks (I used 2 as a failsafe) and then hooked them to the two front most clamps (one on each side) and tightened the clamps down tight (it isn’t going anywhere). I then just ran a single steel zip tie through the top tie down hooks on either side in the back... and the spring clamps just hook into them and keeps the back secure. I just kept the back zip ties slightly loose to allow the clamp to be un hooked for folding the cover back. Took me like 10 minutes and it looks and works fantastically...made my wife super happy. It’s definitely good to hold me over till something else comes out.
im sure I made this sound harder than it is...I can add some pics if needed. Got the steel zip ties at Home Depot for 8 bucks.
