Warning - if you order Rambox, there will be NO Trailer Connections in the bed
Since the Limited defaults to Rambox, I doubt you would get the trailer connectors in bed - and the 5th Wheel / Gooseneck pkg is not available unless you Delete Rambox which would presumable get you the bed connectors
And this last is a big problem for many of us. Further the Coax / FAKRA connector apparently does not work well with splitters / splices - so even if you got creative and found correct FAKRA connector for bed, it would present a problem. I cant imagine MOPAR has not got something in work - hopefully sooner rather than later.
