Hey guys, I have what appears to be a unique problem. I was hoping to install the Bakflip MX4 on a 2020 Limited with Rambox. My installer is saying that I have to purchase different rails from Mopar. I have looked at ~ 500 posts covering the topic of the Bakflip and I have not seen this issue. I'll add pics later, but the rails are the black rails with sliding tie downs. The Bakflip instructions don't specify the need for different rails either. Has anyone encountered this? BTW, the only thing I have noticed is that the rails sit high on the bed.
