Question:

Hi, I am considering the Curt Helux 5th Wheel to Gooseneck part C34HB for my 2022 Keystone Montana High Country 331RL. Estimated loaded hitch weight is 2,400-2,900 pounds. Im currently using the factory pinbox and a BandW companion hitch on my 2024 GMC 2500. 1 Is this model the right one? It shows a 3,200 pound max hitch weight. 2 Will this bolt directly to my factory pinbox bracket? 3 How does this hitch compare to the Morryde Goosetech hitch in ease of connecting/disconnecting? Thanks in advance for your time and assistance.

Hey Michael, thanks for the information. Capacity wise the Curt Helux item # C34HB is exactly what you need for your 2022 Keystone Montana High Country 331RL. As far as fit goes, I'll need some additional information to confirm.

The Curt Helux 5th Wheel to Gooseneck Pin Boxes like item # C34HB are only designed to fit the Rhino-Box bolt pattern. There's no database that shows what pin box bolt pattern you have and Keystone doesn't list that information.

What I'll need you to do is get me the information on the white sticker that's attached to the frame above your current pin box. The sticker should say date of manufacture, weight capacity, and have some form of RPO, LCI, or serial number on it. If you could email me a picture of it or carefully put all that information where it says Add Comment, I can confirm or find the right gooseneck pin box for you. Also if yours says Turning Point or Rhino Box on it just let me know.

The auto latch coupler on the Curt Helux item # C34HB is far superior to the one on the MORryde GooseTech item # MR84MV.

What has you wanting to change over to a gooseneck connection?
