If you jump online and do a search for this very thing, you’ll find a heap of distributors and manufacturers offering just what you’re after. Tonneaus for the Cannon are available in soft and hard formats, made from fibreglass or aluminium, and even versions that offer a roller-top function. If you can’t find what you’re after online, tackle one of the many off-road and ute stores that also stock a range of stuff like this.

If you go down the hard-tonneau route, consider one with central locking that can be paired with the locks on the rest of the vehicle. That way, you’ll have one-button unlocking of the cabin and the tray. It’s a lot less messing around than having a separate set of keys to unlock the cover.
