Thanks for the pictures of your pin box!

Your Fleetwood Montana High Country uses the Lippert 1116 pin box with a 19000lb rating, so for a gooseneck pin box I recommend the Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box - Lippert 1116/1716 - 25K GTW - 4.5K TW # GY48FR which will be an exact replacement.

The only thing you will need to make sure of is that the recessed area around your hitch ball is at least 5" x 5" to allow enough clearance for the Gen-Y to move without interference.

I included a video of the GY48FR for you to take a look at.

My 2017 Keystone Montana has the MorRyde king pin installed which Gen-Y gooseneck system be compatible with its and will it void the frame warranty that is provided by Keystone? Thanks for any assistance you could give me.

@Mike That completely depends what model MORryde pin box you have now. There should be a sticker with the SN and RPO # so if you can provide me with those I should be able to look up what you have. Technically the Gen-Y pin boxes are not approved by Lippert for the frame warranty, but dont let this discourage you from buying one. Lippert cannot simply void your frame warranty just by installing the pin box, you are covered under the Magnuson–Moss Warranty Act. If there was an issue with the frame because of something that the pin box did then that would be a different story but as far as I know, the concerns with the product are not due to the design or potential for error. It installs to the factory pre-drilled holes just as the original pin box.

@JesseM OK it’s not letting me copy and paste my picture of my pin box so I’m gonna let you know numerically S000282594 is the Serial number 4306741 is the LCI item number 9/28/16 is the chassis manufacturing date. RPB 72-1116 is the part # on the pin box .

@Mike Perfect that is exactly what I needed. Your pin box is the 1116 bolt pattern. What is the GVWR of your camper? That is the last thing I will need to know

Hey Randy, welcome back! The factory brake controller in your 2022 Chevy Silverado 2500 is supposed to have a Hydraulic setting. It won't say EOH. That's what you'll need to use with the DeeMaxx Disc Brake Kit w/ Actuator for Tandem Axle…

Hey Mike! It sounds to me like that Rotoflex was worn out and you would have had that failure one way or another. If you're wanting to install a MORryde GooseTech like #MR27MV the disc brakes wont' be an issue. MORryde does thorough testing…

Hey Jarred, thank you for providing that information! The MORryde GooseTech #MR27MV will fit your 2016 Keystone Fuzion M385. However, this is rated for trailers with a GVWR of 18,000 lbs or more. With a 17k GVWR you need the #MR87MV which is designed…

Hey Travis! The right MORryde GooseTech depends on the pin box bolt pattern and GVWR of the Solitude 310GK. If it is a little older it probably has a Lippert 1621, I believe the newer models use the Lippert Rhino. You can ask whoever you're…

Hey Richard. The MORryde GooseTech 5th Wheel to Gooseneck Pin Box like item #MR27MV has not been approved for use by Grand Design. It does not fall under their 5-year limited towable frame warranty that applies to the 2020 and newer 5th wheel…

Hey Scott! Clearance is a concern with the 6-3/4' bed. More than likely you can use the MORryde GooseTech 5th Wheel to Gooseneck Pin Box #MR97MV with the Gen-Y Hitch Gooseneck Trailer Hitch for GM OEM Puck Systems - 5" Offset #GY55XR. To…

Answer 7

Hello Mark; is this a 2019 Grand Design Reflection? Assuming it is, the lowest listed GVWR is 8,995 lbs on the 220RK. The unloaded weight is 6,695 lbs but that isn't what determines fitment, and you're going to be heavier than that no matter…

Hey George. In order to recommend the correct Gen-Y Hitch 5th Wheel to Gooseneck Pin Box, I am going to need the information on the sticker that's attached to your current pin box. The sticker should say date of manufacture and have some form of…

Answer 9

Hello Darryl, thanks for reaching out. You can apply grease to the gooseneck ball, but you would not want to lubricate the pivot points on the Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box #GY48GR. Sadly, there is not much that can be…

Thanks for the picture! I just spoke with my rep at Lippert. Your toy hauler has a 1716 pin box which means you will want the Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box item #GY43FR. This pin box has a 21,000 lbs capacity and a 3,500…

Answer 11

Thanks so much for the photo; based on that I was able to verify with Lippert that what you have is a Lippert 1116 pin box. The correct Goose Box to replace the 1116 is the following: - Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter…

Answer 12

Hey Scott, the correct Reese Goose Box for a Lippert 1116 pin box is the part #RP94716-61301 which does happen to also fit the 1716 since like you noticed they are very close in design and bolt pattern. Not a lot of people know their pin box model so…
