Question:
So i have a 448203RB on a ram 2500 with ramboxes. Is this the correct part for my truck. Your site shows a 48203RB for the MX4. Are there 2 different MX4 models or is mine incorrect. The body shop ordered mine and it doesnt look correct in my opinion.

Hello Jonathan,
I am sorry to hear that you do not like the look of your tonneau cover, as they are not cheap. I am coming up with the same part number for a 2022 Ram 2500 with rambox, it would be our # BAK48203RB which is the manufacturer part number: 448203RB. I have included some pictures of an install that we did here at etrailer, that way you can compare it to how yours looks.
Let me know if it looks the same as the pictures, please. If it doesn't I am going to have you send me some pictures of yours so I can forward them to my contact at Bak Industries so he can tell us if the install was done correctly.
