Bubba,
I like your topper can you give some information on it?
I did what I thought was due diligence research and I found no simple way to buy a hard top that would fit or buy a tonneau cover that would fit in any configuration. I also considered having a piece of tonneau sewed at a sail or fabric shop and set up with snaps, and I couldn’t find what I wanted in the width I needed. My wife was more concerned about security, while my desire was to protect the contents from the elements.
I ended up making the top from marine plywood, possibly overkill, but I finished it with marine epoxy and covered it with the tonneau fabric. I had to make it in panels for the tonneau fabric to fit. If I had it to do over I might go with Line-x or DIY bedliner instead of the tonneau fabric. The tonneau is easy to replace, but it’s not a perfect solution. Bedliner fades so it’s a trade off.
I bought 1x1 aluminum angle from Lowe’s and bolted it to the sides using the existing holes. I added 1/4-20 rivet nuts along the front and two additional on each side for adequate support.
The front and third panel are secured to the angle with conveyor wheels, and rest on HDPE tape to reduce friction. The second and aft panel are hinged and snap to the rail when closed with spring loaded side bolt latches. I get some photos that I can add.
It locks by locking the tailgate, and should keep out the lazy criminals. I felt comfortable with it in hotel parking lots. It’s not totally weather proof. In fact in heavy rain the air flow, I assume, assures that a fair amount of water gets inside. I used, I think, a 1x2 stiffener under each panel and that was probably unnecessarily thick; It limits the height of the cargo put inside. However, I have found pelican cases seem to be the best solution and the biggest that are still manageable to lift without a hernia fit easily. It is clean in appearance and the panels are all inside the sides so if I add a rack, the panels will still open.
