Recommended Replacement For A Rota-Flex Pin Box With 1621 Bolt Pattern On A 2019 Solitude 310GK-R


I currently have the Curt Q24 hitch and my RV has the Lippert Rota-Flex Pinbox. I reached out to both manufacturers and they agree that hitch is not compatible with that type Pinbox. Therefore, Curt recommend a rigid type pinbox. What pinbox would you recommend? 2019 Solitude 310GK-R


Helpful Expert Reply:

You are correct that Curt recently pulled the compatibility approval for Rota-Flex pin boxes with their branded 5th wheel hitches. In place of your Rota-Flex I recommend the MORryde Cushioned 5th Wheel Pin Box for 14K to 18K Trailers w/ Lippert 1621HD # MR84VR. It has a total weight capacity of 18,000lbs and spring capacity range of 14,001lbs - 18,000lbs for optimal ride. It has rubber shear springs that absorb and dampen road shock and vibration and reduce back-and-forth chucking while towing over uneven roads. This helps eliminate jerking when starting and stopping and unlike with internal air bags, this system requires no maintenance.
