After purchasing a used fifth wheel with a Reese Sidewinder I had no idea that there were several different wedges based on hitch model. This wedge fit the A16 perfectly and the Sidewinder works as it should. 412522

  • Best 5th Wheel Hitch for a 2018 Ram 2500 Shortbed to use with a 5th Airborne Sidewinder Pin Box
  • It's not recommended to use a slider hitch with the 5th Airborne Sidewinder, part # RP61422, and they can get a little annoying to operate, which is why the 5th Airborne is such a great pin box upgrade. I recommend using the Curt A25 5th Wheel Trailer Hitch, part # C16046. This hitch drops directly into the underbed rails in the factory towing prep package. With a Gross Towing Weight of 25,000 pounds and a 6,250 pound vertical load limit, you'll be able to handle a lot of different...

  • Can the Reese Goose Box be Used on a Short Bed 2016 Ram 2500
  • The correct Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter for a Lippert 1621 pin box is part # RP94716 for 16,000 lbs or part # RP94720 for 20,000 lbs. With that being said, it is not recommend to use the Reese Goose Box on a short bed truck due to limited turning clearance. They do make an offset gooseneck ball adapter for the Hide-A-Goose Underbed Gooseneck Trailer Hitch part # 9467 on your 2016 Ram 2500, the 5" Offset Ball part # 19308 but this still is more than likely...

  • Recommended 5th-Wheel Hitch for 2017 GMC Sierra 3500 with Factory Rail Kit and Sidewinder
  • Both the B&W 20K Companion # BWRVK3700 and the Curt Q24 # C16545-16025 mentioned in your question are great 5th-wheel trailer hitches. I recommend the B&W # BWRVK3700 for a few reasons. The primary and most important difference between the two when considering your particular setup, is that the Curt Q24 is actually not compatible with a Sidewinder Pin Box. The B&W Companion will work with your Sidewinder without any issues. Aside from that, B&W also has a great reputation in the...

  • Recommended Custom Wedge for Curt A20 5th Wheel Hitch and Lippert Turning Point Pin Box
  • The correct custom wedge for your Curt A20 5th Wheel Trailer Hitch # C16140 is the Sidewinder Wedge # C16992. While we have not had the chance to physically test the Sidewinder wedges with the Lippert Turning Point pin boxes, their designs are extremely similar so this should work without issue. We have also had customers come back to report that other model Sidewinder wedges fit perfectly with their Lippert Turning Point (see attached image). This custom wedge will give you a much...

  • Recommended 5th Wheel Hitch for a 2017 Nissan Titan XD Pulling 11K RV With Reese Revolution Pin Box
  • If your RV has the Reese Revolution pin box that is the first step in the proper way to tow an RV with your 2017 Nissan Titan XD. For the 11,000 lbs of your RV I recommend going with the Curt A16 5th Wheel Trailer Hitch for Nissan Titan XD Towing Prep Package # C16520-16026. This is confirmed to fit the 3 puck system in your Titan XD and is rated for 16,000 lbs towing so you will have no problems at all. Since you are needing to use the Revolution you will also need the Sidewinder...

  • Comparing Reese Elite And Curt A20 Fifth Wheel Hitch for 2013 Ford F-350 with 8-Foot Bed
  • The Curt A20 # C16034 is a high-quality hitch that is going to perform. It has a 20,000 lb GTW and vertical load limit of 5,000 lbs, a secure 2-jaw locking system, and a torsion head which is going to help reduce some of the noise that comes with towing a fifth-wheel. It also has a handy color coding system to tell you when you are ready to couple, tow, and uncouple as well as a height range adjustment between 13" and 17". Keep in mind that with your pin box, you'd need to use the Sidewinder...

  • Recommended 5th Wheel Hitch for 2018 Nissan Titan XD for Trailer with Revolution Pin Box
  • Since your trailer is equipped with a Revolution Pin Box you won't need a sliding 5th wheel hitch in order to gain cab clearance when making tight turns with your short bed Nissan Titan XD. This is because the Revolution will move the pivot point 22 inches back from the king pin to eliminate any cab clearance concerns. For a fixed hitch that will work great on your 2018 Titan XD I recommend the Curt A16 5th Wheel Trailer Hitch # C16520-16026. This 16K hitch is designed to drop right...

  • Can Curt A20 Fifth Wheel Hitch be Used with Reese Sidewinder Pin Box
  • There is a wedge now that does work with the Curt A20 hitch part # C16140 for that you would want the part # C16992. The hitch was redesigned by Curt and they tested it to determine that it now does work just fine with the Sidewinder pin boxes. The head of the system would not wear out prematurely.

  • Recommended 5th Wheel Hitch for 2017 Ram 2500 with Factory 5th Wheel Prep Kit
  • You actually will not need a sliding hitch with a Reese Revolution pin box, since these pin boxes allow for tight turns without interference. A fixed hitch would be ideal, but if you decide to use a sliding hitch, the hitch must be kept in the tow position at all times (never the turning position). Using the Revolution with a sliding hitch in the turning position can cause clearance issues with your tailgate. I recommend going with the Curt A25 5th Wheel Trailer Hitch for Ram Towing...

  • Best Ride Quality and Safest 5th Wheel Towing Setup for a 2016 Ram 3500 Short Bed
  • It looks like you have done quite a bit of research already, so I'll try to fill in the gaps. It is hard to choose one particular setup that is best for any towing situation because there are so many different truck and trailer combinations that you can choose from. We know you are considering a Ram 3500 short bed, but choosing the best towing package will really depend on the trailer you end up choosing. For example, Ram's short bed is actually a little shorter than the 6-1/2 ft. beds...

  • 5th Wheel Hitch Recommendation for 2016 Ram 2500 Short Bed and Turning Point Pin Box
  • Like a Sidewinder, the Turning Point Pin Box has a rotating turret so the pivot point is no longer at the king pin in the hitch, it is 22 inches rearward; because of this it is strongly recommended that you use a fixed fifth wheel hitch. Using the slider would mean the trailer's weight would be pushed too far behind the axle of your truck as opposed to being over the axle or just forward of it, which can put added stress on the truck, hitch, and trailer. For a hitch I highly recommend...

  • Recommended 5th Wheel Rails and Hitch for 2018 GMC Sierra 1500 5.5 Bed for Reese Revolution Pin Box
  • A Reese Revolution is the equivalent of the Reese Sidewinder. The Revolution is the factory installed option and the Sidewinder is the very similar aftermarket option. For a 5-1/2 foot bed, a sliding hitch will not work, so the Revolution or Sidewinder route is the only option to provide you with turning clearance. The really good news is that is by far the ideal option even if you had a longer bed truck. For your 2018 GMC Sierra 1500, I recommend you start with the Reese Quick-Install...

  • Recommended Custom Wedge for Curt 20K 5th Wheel Hitch on 2016 Ram with Factory Rail Kit
  • The correct custom wedge for your Curt 20K 5th Wheel Trailer Hitch like the Curt A20 # C16044 that mounts directly to the factory pucks in your truck bed is the Curt Sidewinder Wedge # C16992. This custom wedge is designed for the Curt A16/Q16 and A20/Q20 5th Wheel Hitches. This is what will be needed to prevent the Sidewinder king pin on your trailer from pivoting in your hitch.

  • Can Curt A16 Fifth Wheel Hitch Be Used with Reese Revolution/Sidewinder Pin Box
  • The Curt A16 Fifth Wheel Hitch # C16120 will work well with your Reese Revolution pin box. The wedge you'd then want for the Revolution that's designed for this hitch is the part # C16992. With this setup you would have great turning clearance.

  • Will Curt A20 Fixed Fifth Wheel Hitch fit in 2017 Ford F-250 Short Bed With Factory Rails?
  • The Curt A20 with Ford OEM Legs # C16034 will fit into the puck system of your 2017 Ford F-250. However, there may not be enough clearance on tight turns and your trailer could very well hit the cab of your F-250, so it is strongly recommended you use a Sidewinder with this hitch as a way to protect your cab from damage. Otherwise, you may want to consider Curt Q20 # C16530-16020, a sliding hitch which also fits in the factory puck system of your '17 F-250. Should you want to go with...

  • Lightweight 5th Wheel Hitch Option for a 2018 Ram 3500 Short Bed with the Factory Prep Package
  • I do have a really good option for you but the two you listed cannot be done safely. The Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter part # RP94720 cannot be used on your 2018 Ram 3500 because it has a short bed. If you were to use the Reese Goose Box the loft of your trailer would likely come into contact with the cab of your vehicle causing thousands in damage. The Demco Recon Gooseneck-to-5th Wheel Trailer Hitch Adapter part # DM8550045 cannot be used with a rotating...

  • Can the Curt Q20 5th Wheel Hitch Work With a Reese Revolution/Sidewinder Pin Box
  • I have a solution for you, but the Curt Q20 Hitch # C16530-16025 for the 2017 GMC Sierra w/Factory Rail Kit is not compatible with rotating pin boxes like the Reese Revolution and Sidewinder pin boxes. With that said, Curt does have the A20 5th Wheel Hitch for the Chevy/GMC Factory Towing Package, # C16064, that is compatible with the Reese rotating pin boxes. You will need to use the Sidewinder Wedge for the Curt A16 and A20 Hitches, # C16992, at the hitch and pin box connection. The...

  • Why is Reese Sidewinder Pin Box Not Compatible with Curt Q Series Hitch?
  • The rotating pin boxes like the Sidewinder Fifth Wheel King Pin with Rotating Turret by 5th Airborne, 16K # ST400-SW16K are not compatible with the Curt Q series hitches because of the hitch head design that had a unique spherical axial bearing. That system allowed too much movement for any of the rotating pin boxes to be compatible. If you already have a Q series hitch, I recommend simply changing the head of the hitch with the Curt A series 16K # C16520 or 20K # C16540. Either...

  • Recommended Sidewinder & 5th Wheel Hitch For 2017 Ram Mega Cab and 2015 Forest River Vengeance 320A
  • For your 2015 Forest River Vengeance 320A Super Sport model and your 2017 Ram Mega Cab with 64 inch bed, I have the solution you are seeking to ease your mind. Let's start from the beginning with rails and a hitch. If you have the factory rails, then I recommend the Curt A16 5th Wheel Trailer Hitch for Ram Towing Prep Package - Dual Jaw - 16,000 lbs # C16520-16021. If you don't have the factory pucks, then I recommend the Reese Quick-Install Custom Base Rails and Installation Kit for...

  • Does Curt Fifth Wheel Work With Reese Revolution on 2017 Ram 2500?
  • In order to use the Curt A16 # C16520-16021 with a Reese Revolution you will not need an adapter, but you will need wedge # C16992. This wedge bolts onto your Revolution to prevent the king pin from rotating in your Curt fifth wheel hitch. That wedge would be all you'd need to tow your new fifth wheel trailer with the Curt hitch and your '17 Ram 2500.

  • 5th Wheel Trailer Hitch for 2018 Ford F-150 5-1/2 Foot Bed and Grand Design Reflection 150 Series
  • The Lippert Turning Point pin box on your trailer means that you will need a fixed 5th wheel hitch for your 2018 Ford F-150. The Curt A16, # C16120, is a great option for you. This hitch is rated at 16,000 pounds, so it has plenty of capacity for the Grand Design 150 series of trailers. The dual jaw design is safe and secure and the cushioned head improves ride quality. For the best fit with your Turning Point pin box I also recommend using custom wedge # C16992. For an installation...

  • Recommended Reese Sidewinder Wedge for Curt A25 5th Wheel Hitch
  • The Sidewinder Wedge for Curt A series 5th Wheel Trailer Hitches # C16992 is the same wedge that is used for the A25 model as well. I reached out to my tech contact at Curt to confirm. The A-Series hitch heads all have the same connection dimensions, so the custom wedge will be far better than the universal fit.

  • Recommended 5th-Wheel Hitch that is Easily Removed on 2014 Ram 1500
  • Choosing the right 5th-Wheel Trailer Hitch for your 2014 Ram 1500 will depend first on the weight of the trailer you plan on towing. You will want to make sure the truck and hitch have weight capacities that exceed the trailer's loaded weight. Since your Ram 1500 has a short 5-1/2 foot bed, the safest way to tow a trailer is to use a stationary 5th-wheel hitch and replace the pin box on the trailer with a Sidewinder, if it does not have one already. The Sidewinder will be required to...

  • Whoever told you that was incorrect (and possibly trying to sell you a sliding hitch?) because the Husky Silver Series 16K W 5th Wheel Trailer Hitch # HT31326-31314 will fit - and work - in the Reese Elite Series Underbed Rail Adapter # RP30156 that fits the factory puck system of your 2015 Ford F-250 Super Duty. The only thing to note is that using the Silver Series 16K W with your Reese Revolution (which is the OEM name for a Sidewinder) will reduce the vertical load limit of the...

You can tow your friends and family's campers with this hitch allowing you the turning clearance needed. This will also work with a Sidewinder as long as you keep it locked in the front towing location at all times and use the wedge # C16992.

Therefore, the only option you have is the above bed base rails which I know is not what you want but unfortunately, your only option. The base rails can be a pain if you need to slide something in but other than that they really don't take up much space.

The combination of a fixed hitch with Sidewinder # RP61412 will give you 22-inches of additional turning clearance, as compared to the clearance provided from most sliders, which is about half that amount.

To mount it in the factory puck system of your 2015 Ram 3500, you would want the Reese Fifth Wheel Rail Adapter # RP30154.
