That cover looks really nice on your truck.

Mom and Dad have something similar on their trucks and they're a gas mileage eating sail when they're open for loading cargo in the bed.
They are a lot more secure than the roll up canvas tonneau so it's a trade off. Not downplaying that at all.
Securing what's left in the bed overnight is a serious consideration and canvas is not as secure as the solid panel covers.

Can you remove the folded panels to load cargo in the bed and drive or is it permanently affixed to the side rails?
The last third of Mom's bed cover doesn't fold up and it can't be removed without removing the side rails. Dad and my stepbrother have what looks like the same cover so I assume theirs are the same animal.
A way to remove them once they're folded while remaining reasonably secure would go a long way toward selling me on one of these for my next bed cover.
