Ram Trailer Tow Prep Package

Fifth-wheel hitch mounted on part RP30154 on Ram Tow Prep

Ram offers an underbed mounting system for fifth-wheel hitches as an option on new trucks starting in 2013. This system is designed for maximum convenience and versatility. The entire mounting system is located underneath your truck bed - no parts extend above it. The system will let you hook up a fifth-wheel hitch or a gooseneck ball.

The underbed mounts give you full access to your truck bed when you're not towing. When you want to tow, you install a hitch that fits into the pucks in the bed, or you can get an adapter that fits into the pucks and has slots to fit any standard fifth-wheel hitch.

Fifth-Wheel Adapters and Hitches

To install most industry standard fifth-wheel hitches available at on your Ram truck with factory tow prep package, you'll need to install part number RP30154 (rails), pictured above left. This part removes easily so you can still have a clutter-free bed when you're not towing. Hitches that fit directly to the factory mounts without the need for a separate adapter are available (pictured above right). Refer to the following table to find out more about these hitches.

I have a 2012 ram 3500 it has holes in the bed for a fifth wheel hitch and 2012 did dodge install holes and this as a kit what was this done afterwards

David B.


It is probably aftermarket. The OEM prep kits for 5th wheels(puck system) didn't start rolling out until 2013.

John H.


@WilliamK What is the distance between the holes on center?

Stan K.


I traded my 2017 Ram Laramie with factory puck system for a 2020 Ram Longhorn with puck system. Will the B&W hitch fit?

David B.


Is your Ram a 1500, 2500 or 3500 and what is the bed length? What version of the B&W do you have?

John H.


@StanK Dodge never changed the design or shape of their puck system. If you used the B&W hitch in your 2017 Ram, then it will fit in a 2020 Ram.

I have a 2021 Ram 2500 with a factory installed puck system and a Ram m20 fifth wheel. My trailer is a 37' 2021 Flag staff classic. With a turning point pin box. It pulls great ,the issues I'm having is when I'm making sharp turns. The fifth wheel has some side to side play causing the pinbox which is locked to the fifth wheel to shift hard to the left or right. Is there anything I can do to stop this? Thanks.

David B.


Do you have any suspension enhancement on your truck and 5th wheel? How many miles are on the 5th wheel? Are these turns on flat level surfaces? Just need to make sure your not "off-roading" lol.

Jerome R.


My truck does have air bags. The fifth wheel is stationary no slide on it no I have not been offloading lol. I have towed with the fifth wheel about four trips proximately 18 hours. Most of the towing is on flat ground and the shifting I get is when I’m making a sharp turn.

David B.


Well you could add some Timbren Trailer Suspension Enhancement System Medium-Duty Trailers 7,000 lbs # TTRA1032 .

I have a 2021 Ram 2500. I am wondering if the B&W Slider part BWRVK3400 would fit in my factory installed trailer tow prep package? I want to easily go from the fifth wheel to the gooseneck

David B.


The B&W Companion Slider Gooseneck-to-5th-Wheel Trailer Hitch Adapter - Dual Jaw - 20,000 lbs # BWRVK3400 is designed to work with B&W Turnoverball Underbed Gooseneck Trailer Hitch w/ Custom Installation Kit - 30,000 lbs # BWGNRK1320 . If you have an OEM prep you would need something like # BWRVK3670 or # BWRVK3600 .

I have a 2012 RAM 2500 with RAM Boxes & 6-1/2 foot bed. Is there an option for a fifth wheel hitch that can be used with a Reese Sidewinder pin box?

Les D.


Most 5th wheel hitches can be locked out from rotating so a Sidewinder can be used. Do you already have a Sidewinder - or do you neeed a recomendation for a fit? If so we will need the pin box number. This is typically a 4 digit number stickered on your current pin box flanges or pin box. Could be like 1621, 1716, 1116, or other. You'd then need to use a fixed hitch like the Reese part # RP30047 with the wedge # SWW-03 plus a fifth wheel rail install kit part # RP50054-58 and you'd be set.

David N.


@LesD I do have the sidewinder. Appreciate the advice on the fixed hitch, rails and wedge. Many Thanks!
