2018 Ram 3500

I've bought 2 Reese Quick Install kits this year, the sales reps at etrailer were very helpful.Shipping times great. Did have wrong bracket in one order, was taken care of promptly.



by:

Very poor design for the Ram 3500. The front brackets have four holes to secure the rail. Two are used and the other two bolts use spacers and the bed to secure the rail. Should be designed to use all of the bracket for a stronger hold on the hitch.



by:

Front brackets do not have a specific spot they can be installed, So it just makes it harder to line up properly before drilling into your bed



by:

Very good no problem installing every so often just go over the bolt on the frame of truck for tightness



by:

Excellent, well built, well designed kit. Install went without any issues.

  • 5th Wheel Trailer Hitch Installation Kit for 2015 Ram 3500 Dually and Reese Hitch
    As far as fits go the situation was that on Curt kit # C16430-204 they had excluded dually models. But we have installed this kit on a dually model and have been told by Curt recently that it will fit. So if your 2015 Ram 3500 does not have the factory prep package for a 5th wheel hitch, you should be able to use this Curt kit. And your Reese hitch will fit it. But I can tell you that Reese installation kit, # RP50085-58, will fit dually models for sure and your hitch will fit this installation...

  • Easiest to Install Fifth Wheel Rail Kit Recommendation for 2018 Ram 3500 Long Bed
    We do have custom fifth wheel bracket kits that fit your 2018 Ram 3500 but you'll need to make sure that the rails you have are Reese since we can't recommend mixing rail and bracket manufacturers. If you do have Reese rails all you'd need is the bracket kit part # RP50085 which is custom fit for your truck. If you have a different brand of rails are you aren't sure what you have then we have to recommend you go with an all new rail kit part # RP50085-58 which gives you the same bracket...

  • Fifth Wheel Rail Kit Recommendation for 2018 Ram 3500 Short Bed
    Reese has three rail kits available for your 2018 Ram 3500 short bed with the Ramboxes. The one I recommend is the part # RP50085-58 as it is a custom install kit that will give you the smaller dimension rails. The part # RP56010-53 is a kit that has brackets that install on the outsides of the truck frame which makes it a bit easier to install but the rails are bigger. The part # RP30035-520 is a semi custom kit that will be much more involved to install. Since you have a Rambox truck...

  • Will Demco AutoSlide 5th Wheel Hitch Fit with B&W Turnoverball Gooseneck Hitch?
    The Demco Hijacker Autoslide 5th Wheel Trailer Hitch w/ Slider - Single Jaw - Above Bed - 21,000 lbs # DM8550035 is not compatible with the B&W turnoverball gooseneck hitch # BWGNRK1314. The handle for the gooseneck ball will not work with the 5th wheel rails in place according to my contact at B&W. Unfortunately you will need to choose between them. If you go with the above bed rails, I recommend the Reese Quick-Install Custom Base Rails and Installation Kit for 5th Wheel Trailer Hitches...

  • Recommended 5th Wheel Hitch for MORyde Orbital Pin Box on 2019 Forest River Arctic Wolf
    The MORyde pin box RSPB83-1622 is a 16K orbital rotating pin box designed for increased turning clearances with short bed trucks. Although this nice feature is not required for a long bed truck like your 2017 Ram 3500 I recommend keeping it. The Lippert Center Point suspension # LC1565391 will handle much of the road shock, so I recommend keeping your additional turning clearance and simply using a really nice 5th wheel hitch. If you have the factory puck system in your Ram, I recommend...

  • Fifth Wheel Rail Kit for 2018 Ram 3500 Short Bed
    So for your 2018 Ram 3500 we have semi custom rail kits like the part # RP30035-520 and fully custom fit kits like the # RP50085-58. The semi-custom kit is the easiest on price for sure but it requires quite a bit more time and involvement for the install. There will be frame drilling etc. Whereas the custom install kit will utilize holes already present on the frame for a much simpler and easier install.

  • Can Trailair Rota-Flex Pin Box be Used With Andersen Ultimate on 2021 Ram 3500
    You can use an Air Ride like # LC158778 with the with the Andersen Ultimate Connection 5th Wheel Trailer Hitch System with Adapter # AM3200, or for a Trailair Rota-Flex pin box like # LC328330 it would need a lockout kit from Andersen in order for it to be compatible as this prevents rotation that would cause damage. I have added a link below to our selection of Trailair pin boxes for you in order to find the correct replacement. Having said that, while the Andersen can be used, it is...

  • Can a Single Attachment Point B&W Companion 5th Wheel Hitch be Used with a Sidewinder Pin Box
    You actually shouldn't be using a B&W Companion hitch with a Sidewinder at all. The problem is because of the single attachment point and the force applied to the hitch from the Sidewinder it could cause the gooseneck hitch under the bed to get damaged or even break free causing the whole assembly, including the Companion, to rotate. The only difference between the regular Companion and slider is that the slider can slide back to allow more clearance between the truck and trailer when...

  • Will the B&W Companion Work With Sidewinder On 2018 Ram 3500 with RamBox
    I do have an option for you but in order to tow a fifth wheel trailer using a truck with RamBox like a 2018 Ram 3500, you'll have to go with a pin box with rotating turret as that's the only way to clear the bed sides. Pin boxes with rotating turrets like the Reese Sidewinder cannot be used with gooseneck to fifth wheel adapters like the B&W Companion. Therefore, the only option would be a new fixed fifth wheel hitch. I recommend the Reese M5 5th Wheel Trailer Hitch part # RP30928 with...

    For your 2014 Dodge Ram 3500 we have Reese rail kits that are a confirmed fit that will work perfectly with your Reese 14k fifth wheel hitch. For that your best option is a custom install kit as it will minimize install time and drilling. So you'd want the Reese kit part # RP50085-58 which is the correct kit for your truck.

  • Install Kit for Reese Titan 16K On a 2013 Ram 3500 SRW and DRW
    Yes, the Reese Quick-Install Custom Installation Kit part # RP50085-58 is a fit for a 2013 Ram 3500 (SRW and DRW) and will work perfectly with the Reese Titan 16 5th Wheel Trailer Hitch part # RP30866. The Reese Quick-Install Custom Installation Kit is a custom fit kit so there will be no cutting or drilling into the frame. We also have the 5th Wheel/Gooseneck 90-Degree Wiring Harness part # 50-97-410 which will be good to have as well. If you by chance have the factory in-bed pucks then...

  • Recommended 5th Wheel Hitch And Sidewinder For A 2021 Ram 3500 With RamBoxes
    I still recommend using a rotating pin box due to your 2021 Ram 3500 having RamBoxes. The weight capacity of the pin box and the 5th wheel hitch are the other important factors here. Since you don't have a camper yet you don't know what the GVWR is. The Reese 5th Wheel Trailer Hitch # RP30047 I recommended before has a GTW of 16,000lbs and the Reese M5 5th Wheel Trailer Hitch # RP30928 has GTW 20,000. You can always go high and get the heavier weight capacity hitch but it will cost you...

  • Recommended 5th Wheel Bracket and Hitch for a 2020 Ram 3500 with RamBox
    I'd be more than happy to help you out! I have bracket and 5th wheel hitch recommendations for you, but since your 2020 Ram 3500 has the RamBox upgrade you're also going to need to swap out your OEM pin box for one with a rotating turret like what we find with the Reese Sidewinder. If you were to use a standard pin box it would hit the rides of your truck bed, but since the Sidewinder rotates above the sides of your bed it takes care of this issue. For a bracket kit I recommend using...

  • What Is The Difference Between PS30133 and PS30121
    The difference between the Pro Sereis # PS30133 and the # PS30121 is that the PS30133 includes the rail kit. They are going to be the exact same hitch but the difference in price is that a basic mounting rail kit is included. If you wanted a custom installation kit for your 2014 Ram 3500 that will install with minimal drilling you'll want to use the Reese # RP50085-58, which will also put industry standard rails in your truck bed that allow you to mount a 5th wheel hitch.

  • Fifth Wheel Rail Kit Recommendation for a 2015 Ram 3500 to Install 22k Reese Fifth Wheel Hitch
    To install the Reese 22k Fifth Wheel Hitch part # RP30033 in your 2015 Ram 3500 without the factory rail kit will only require you to install the correct fifth wheel rail kit. For that you would want the custom install kit that will minimize drilling on your vehicle and will cut install time considerably. For that you would want part # RP50085-58.

For your 5th wheel hitch, I recommend the Reese M5 5th Wheel Trailer Hitch # RP30928 which will work very well with these rails and will give you a very strong and reliable hitch. You will also need a Sidewinder Pin...

  • 5th Wheel Rail Kit Confirmed To Fit 2017 Ram 3500 6 Foot Bed Without Factory Rail Kit
    For your 2017 RAM 3500 6 foot bed, the rail kit # RP50085-58 is a confirmed fit. If you want the easier to install outboard kit, the # RP56010-53 is also a confirmed fit. The benefit of the longer rail of 48 inches versus the 43 inch rail is ease of install, but length of rail could be a drawback depending on your perspective.

    In order to use the Reese 5th Wheel Trailer Hitch part # RP30047 on a 2013 Dodge Ram Pickup, I recommend the Reese Quick-Install Custom Installation Kit part # RP50142-58 for 1500 models, part # RP56011-53 for 2500 models, or part # RP50085-58 for 3500 models. This route would not require any drilling into the frame.

  • Fifth Wheel Hitch Rail Kit for Husky Hitch in Bed of 2016 Toyota Tundra 6.5 ft Bed
    For a set of fifth wheel rails that fits your 2016 Toyota Tundra with a 6.5 foot bed the best option is a custom install kit as it will minimize drilling and install time. For that you'd want the Reese kit part # RP50085-58 which is a fit for your truck and also provides the style of rails that your Husky hitch requires. Husky makes a universal style rail kit that fits your truck too but since it will be a much more difficult install and the Reese kit works just as well it would be your...

  • Custom Fit 5th Wheel Base Rails and Installation Kit for 2015 Ram 3500
    The 5th wheel hitch base rails and custom installation kit I recommend for your 2015 Ram 3500 is the Reese Quick-Install Custom Base Rails and Outboard Installation Kit # RP56010-53. The custom installation brackets will not require you to drill into your vehicle's frame, and the outboard orientation of the brackets will make it easier to access the installation hardware. These base rails are industry standard rails, so they will work well for your Husky 24K 5th Wheel Hitch. If you're...

  • Can 2018 Ram 3500 with Ram Box Tow Fifth Wheel Trailer.
    The problem with the Ram Boxes is that they make the bed rails so narrow that you can't make turns with a fifth wheel trailer even if you are using a Goose Box. Normally we have to recommend people use a Sidewinder pin box replacement as it's the only pin box that pivots higher and prevents interference with the Ram Boxes. Since you are installing a Goose Box that means you'd have most likely the Lippert 1621 style pin box and the Sidewinder you'd need is part # RP34FR or you have the...

  • Is Valley Powerpull 5th Wheel Hitch Compatible with Reese Industry Standard Truck Bed Mounting Rails
    The Reese # RP50085-58 bracket/rail kit is compatible with your truck. If memory serves correctly, the Valley PowerPull was compatible with the industry standard bed rails that Reese (and other companies) uses. You can confirm this for yourself by measuring the spacing of your hitch mounting tabs that insert into the rails front to back and side to side, center on center. Compare the results with the photo I've edited for you. The tabs, when measured front to back should be about 22 inches...
