Mor/Ryde Pin Box

I just installed a Mor/Ryde RPB72-1621HD-03 pin box and it hasn't cured the chucking nor the start-stop crunch. The trailer is a 2012 Rockwood 8280WS 5th wheel with a empty weight of 7,503 pounds, a max weight of 9,134 pounds with a typical load under 8,500 pounds. I tow with a 2012 Ford F-250 Super Duty with less than 5,400 miles (I don't believe the truck is the issue). The 03 pin box is the lowest rated max trailer weight per the manufactures chart shown as 11,500 pounds. I think that the manufacture wasn't prepared for the new ultra lite 5th wheel trailers and that the shear spring in the box is to heavy for the light weight. Other than the manufacture hasn't responded to my last 3 emails requesting help I feel like I'm on my own. Has anyone had this same issue but most of all has Mor/Ryde been of any assistance? To say the least the Lippert pin box is lighter and the Mor/Ryde offers no improvement to the chucking with an additional 70 plus pounds of added weight.

I have a Rockwood 8285ws. Very similar to your trailer. I also have a 2013 F250. I changed to a Mor/Ryde early this year & can't believe the difference it made. Chucking & banging almost completely illuminated. I have the Ford/Reese non sliding hitch. If you have the Ford hitch make sure the anchor pins are adjusted properly so there is very little to no play.
