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.

@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

Hello Lanny, thanks for reaching out. The CRE 3000 is already a pretty good suspension system, but if you want to upgrade, the first thing that comes to mind are the AllTrek 4000 equalizers. They have more rubber than the CRE 3000, 40% more, so you…

The #MR78ZR kit is designed for the older RE suspension and won't work with your setup. You have the LRE4000 if you have the #20 shear springs. You will still need to replace the rubber shear spring with the #MR79UR. Then you can use upgrade kit…

Answer 12

You can use 8k springs on a trailer that has 7k axles. You'd just have a little more spring capacity than needed. If the dimensions of your springs are the same as the part #DX74XR springs then you would not need new hangers. Worth mentioning is…
