Question:

Good day, Whats the difference between the MORryde pin box RPB72-1116 and the RPB72-1621HD

Hey Bruno, the big difference is that the 1116 style is considered a medium length and the 1621 is considered a long pin box. It's not by much but the 1621 sticks out about 3 inches more than the other one. The bolt patterns are different too so you wouldn't be able to swap from one to the other. Which do you have?

None, I still have the original from Montana but I'm looking for something that could give me a better ride like this RPB72 but I'm a bit confuse on wich one could fit on my 5th wheel. My rig is a Montane 3812ms 2020. Regards ! Bruno

@Bruno Thanks! I can tell from that you have the Lippert 1116 pin box which means for a MORryde you'd want the part # MR87VR. This will make a huge difference in ride quality!

@Bruno You would use the hardware that is currently holding on the pin box with the new MORryde. These do not come with new hardware for that reason.
