I have just finished putting on a Pace Edwards roll - top tonneau cover. It is one of only two that I know of that I could install and wouldn't interfere with my Back-Rack. It has a lock, but the question is: How do I lock the tailgate? What has anybody used that they are pleased with? I see a lot of Ford trucks with a keyhole in the tailgate handle - What, we got the Cummins, they got a lockable tailgate? I guess we had to sacrifice something... ... ... . The parts man at the stealer said the only lock that Dodge had went with the Mopar hardcover tonneau so that doesn't help. Anybody know of an after market lock for the Dodge?
