Convert a ball on roto flex pin box
hello all,
new to this forum. i used to have a 2001 Komfort fiver that i converted to gooseneck using a covert-a-ball adapter. It had a standard pin box, no cushioning or movement. it worked really well for me, keeping my truck bed more useful for work. towed very well. truck is 2017 ram 4x4 CCLB 2500 6.7 cummins w/factory gooseneck prep package.
I donated that trailer to a CA fire victim and now i am buying a 2021 crossroads ce3201rl 36' fifth wheel with the "roto flex pin box" i am aware the conversion will probably void some pin box warranty, but I really like popping the ball out of the bed vs a 180lb hitch. the goose neck adapter has the following capacities:
- Towing Capacity 20,000 lb. GVW
• Tongue Weight 4,000 lb.
• Cushioned 360˚
• Safety chains included
Question is: Have any of you had any experience converting a roto flex pin box?
that pin box has some additional movement capabilities, seems fine to me, but if someone has some practical knowledge that would be great.
Thanks, and happy new year!

I took this picture of a hitch setup in Yuma in January 2015. It had me scratching my head a bit. Goose Box pin box is the only one I think Lippert warranties. Chris

My understanding is that any type of rotating pin box and gooseneck are not a good idea. I would replace the rotating pin box with a standard and use your gooseneck adapter of buy an Andersen Ultimate. That is what I use and am very happy with it.

Anderson makes a “locking ring” for use with the rota flex if I remember right.

Agree, looks like 1 too many hinges.

My mistake, I thought the Roto Flex pin box pivoted side to side where only the pin waggles its head up and down. Andersen makes a "kit" (two bolts/nuts) that keep the pin box head from wagging.

Check out the Reese Goosebox, it's approved by Lippert & it's also cushioned. Remove the RotoFlex & sell it to someone with a standard pinbox, you'll both get upgraded.

Thanks George!
And thanks to everyone that weighted in!
It looks to me like the kit will isolate the movement and that will make it preform as designed. i like that its easy to install!
My convert a ball is exactly what is shown in Snoking's picture. It is different and people have asked me about it often. I was amazed at how robust the conversion was. I logged thousands of miles and many were on dirt roads & rocky, bumpy, backroads. Also when i removed the conversion kit there was no damage to the pin or pin box. Thanks again everyone!
