Question:
MORryde Cushioned 5th Wheel Pin Box for 11.5K to 14K Trailers w/ Lippert 1621 and 1621HD Part Number: MR74VR My rig, 2020 Grand Design Reflection 311BHS has a 13,995lb GVWR and a Lippert 1621 pin box. Would the MORryde MR74VR be the correct model for my RV? Is there any length difference in the stock 1621 pin box and the MR74VR pin box?

Hey Ted, thanks for reaching out, and thanks for providing all of that info on your camper. Sounds like you are already on the right track because the MORryde Cushioned 5th Wheel Pin Box # MR74VR is exactly correct for your 2020 Grand Design Reflection 311BHS. This pin box uses the same 1621 bolt pattern and is correct for the 13,995lb GVWR. There will be no length difference between this and your stock 1621 pin box, but it will offer better ride quality.

Hey Ted, how did the MORryde cushioned pin box work out on your Reflection? It’d be great to hear if the ride quality improved as expected. Your feedback could help others looking to upgrade their 1621 pin box too.
