Question:
Just finished watching the video 4 Offset Ball for B and W Turnoverball Gooseneck Trailer Hitches on a 2021 Ram 2500 Video. My truck is the 2021 Ram 3500 with 65 bed. Do I need other parts than the offset ball to mount in my truck. If so which parts and any video instruction how to connect. I take it the OEM center hole in bed cannot use?

Hey Rudi, thanks for reaching out!
I think what you're saying is you have the OEM puck system with the center gooseneck hole installed on your 2021 Ram 3500. If that's the case, then I recommend using the Gen-Y Hitch Gooseneck Trailer Hitch # GY83XR which comes with a 5" offset - the 4" Offset B&W Ball # BWGNXA4085 is designed to only work with the B&W gooseneck hitches like part # BWGNRK1320 that fits your truck.
You can replace your OEM puck system with the B&W gooseneck, but I don't really think it's work it since there are already offset solutions for your truck - please let me know if you have something different.
You should have enough offset for turning clearance, but we also have a formula you can use to make sure that you can safely use an offset hitch ball as opposed to needing a sliding hitch:
Clearance Formula - (A + B) - C = Clearance
A = Distance from center of fifth wheel hitch jaw to truck cab
B = Length of offset (slider clearance or Sidewinder offset)
C = Width of trailer divided by 2 (to get half)
You need at least 4" of clearance to be able to make a 90 degree turn.

Hey Rudi, how did things go with the Gen-Y gooseneck hitch on your Ram 3500? Did the 5-inch offset give you the turning clearance you needed? Your update could make it easier for others working with the OEM puck system.
