not sure about the oem one but i do know that the truxedo truxport does work with the CMS Rails system, as it is the one i have on my truck with 2 of the side storage tool boxes. As long as it sits on the top of the bed rails it should work, if it mounts to the inside of the bed rails some of the accessories like the side storage tool box will not work for it does not have enough clearance.
