Which MORryde Cushioned Pin Box Fits 2019 Reflection 337RLS
Updated 03/31/2026 | Published 03/26/2026
Question:
A friend just purchased a new 5th wheel and is replacing the Morryde RPB72-FB with a goose neck pin box he purchased from e-trailer. I am wondering if the RPB72-FB will fit my 2019 Reflection 337RLS. I understand that it is more than I need, but is better than the stock pin box and if it will fit I can get it for cheap. Thanks for your help!

Hey Don, are you sure the pin box part number of the MORryde is RPB72-FB? Usually it's a lot longer of a part number after the 72 which tells us which pin box model it is. Your 2019 Reflection 337RLS would have the Lippert 1621 pin box though so if the next part numbers are 1621 it would work for you. The part # MR84VR is an example of a MORryde cushioned pin box that fits your 2019 Reflection 337RLS.

Thanks for the reply Jameson. The etrailer part number for the pin box I'm talking about is MR55QR. Would I be able to get this to fit on my Reflection? The bolt pattern looks the same as the MR84-VR..? Thanks again!
