3500 Dually Conversion

[Alan Sunderland]

I have a 2016 3500 Dually that got the drivers side bed banged up on. I do a lot of towing, a 35' fifth wheel camper and a 30' goose neck horse trailer. I am interested in converting it to a flat bed. The problem I am having is the after market flat beds cannot utilize the integrated puck system. Does anyone have any experience with this?? I purchased the Reese system to utilize the my fifth wheel but people have told me that I would need to but the fifth wheel to goose neck converter??? Looking for any advice.

Thanks
Alan
