Replacement Pin Box For Gooseneck Towing a 2023 Grand Design Momentum 320G 5TH Wheel Toy Hauler

Question:

I am picking up a 2023 momentum 320G and want to change the pinbox to a gooseneck pinbox. What is the model number I need since the dealership I think is trying to get over saying I need a 21K lippert which I know reese doesnt make a 21K bag system so it seems like they are trying to sell me a less money one at the more money price. Please help.

Currently the Gen-Y Hitch 5th Wheel to Gooseneck Pin Box # GY98GR is the best option for replacing your Lippert Rhino Box Pin Box on your 2023 Grand Design Momentum 320G 5th wheel toy hauler. Reese does not make an Goosebox that is compatible with the Rhino Box mounts. This pin box uses rubber torsion springs to give a cushioned ride. The box is rated for tongue weights of 1,500-3,500lbs and a maximum trailer capacity up to 21,000lbs. Your Momentum has a dry hitch weight of 2,300lbs and maximum weight capacity of 16,800lbs.

You will need a set of Safety Chains # GY49GR as well since ball connections require safety chains.
