Video Transcript for Reese Fifth Wheel Installation Kit - Custom - RP50142-58 Review

Today we're going to take a look at the Reese Quick Install Custom Base Rail Lean installation kit for the fifth wheel trailer hitches. This is a custom fit part. It is designed to fit the Dodge Ram 1500 Truck starting in the year 2009. Now on a custom fit part I always like to recommend to go to our website, use our fit guide, put in your year and model vehicle and it'll show you if this would work for your application. Now this kit includes the custom brackets, the rails, and all the installation hardware. Now the custom brackets, which are these parts here, are designed to mount beneath your truck bed and they do provide the attachment appliance for all these fifth wheel layers. The brackets themselves are vehicle specific.

They mount to existing holes in your trailer frame and because of that it will minimize the drilling and measuring when installing these so it does cut your installation time in half when compared to the universal bracket systems. Now the base rails themselves, which are attached to these brackets, they will sit in the truck bed and they allow the installation of the fifth wheel trailer hitch to your vehicle. Compatible hitches that will fit are the curt, the draw type, the hidden hitch, the reese, the valley, and the husky. One note I do want to let you know is that they will not fit the Reese Elite series or the Valley UBS hitches. The finish on all these parts is a nice black powder coat finish to help resist corrosion and as I mentioned it comes with the installation hardware for the rails, installation hardware for the brackets, and a nice set of detailed instructions on how to install all this. That should do it for the review on the Reese Quick Install Custom Base Rails and installation kit for fifth wheel trailer hitches..

It takes about 4 hours to get it installed and was fairly easy. Fits like a glove and works and looks great. 496482

I have installed this kit on a 2012 ram 1500 quad cab. the rear bracket is a bit challenging to get in place, and if you have dual exhaust there is no place to reinstall hanger bracket, other than that its a easy install 86233


Comments

what did you do about the hanger? do you have one custom made later? Hangers provide support on the exhaust system. without them you can break manifold parts from stress.

Kind of a complex install and having to remove wheels, rear liners and the spare make it kind of a difficult job. Local installer did it which was worth the 175$. Except they didn't really use the correct hardware or bolt locations which is annoying. Very careful of wire routing as it pinched the air suspension sensor wire and created all sorts of headaches. Anyways functionality wise it's a good system and good price and or price match, (ebay was a bit cheaper). I pull a 30ft Trailer 9k+ and it doesn't leave me questioning anything.

Ask the Experts about this Reese Fifth Wheel Installation Kit
Do you have a question about this Fifth Wheel Installation Kit?


  • Fifth Wheel Hitch Mounting Brackets for 2016 Ram 1500 Short Bed
  • The recommended frame brackets for your 2016 Ram 1500 are part # RP50142. The bracket kit includes the hardware to attach the brackets to the frame, but the hardware to attach the hitch mounting rails in the bed to the frame brackets is sold separately as part # RP58430. The hardware is meant to be used one time only, I wouldn't recommend reusing your old hardware. To install a 7-way trailer connector in your truck bed, use part # 41157.

  • Lightest 5th Wheel Hitch With Clean Truck Bed on 2017 Ram Standard Bed Crew Cab
  • To give you the clean bed you are looking for, I recommend the Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches # BWGNRK1309-5W and then using the B&W Companion 5th Wheel Trailer Hitch - Dual Jaw - 20,000 lbs # BWRVK3500-5W. This hitch can be installed with the hitch head separate. This will give you the cleanest bed. If you want the lightest option with a clean bed, then I recommend the same gooseneck hitch, but then use the Curt X5 5th Wheel Base Rails...

  • Will Sidewinder Allow 2016 Ram 1500 With Rambox to Make 90 Degree Turn?
  • In order to determine if a Sidewinder such as # RP61420 will allow you to perform a 90 degree turn with your 2016 Ram 1500, you first need to measure the distance from the center of your fifth wheel hitch jaw to your truck's Rambox.You will also need to know the width of the trailer you will be pulling. You can then use this formula to find out if you can do a 90 degree turn: (A + B) - C = Clearance A = Distance from center of 5th-wheel hitch jaw to Rambox in inches B = Length of Sidewinder...

  • Fifth Wheel Hitch and Sidewinder Recommendation for 2017 Ram 1500 5-1/2' Bed
  • The Max Turn Technology feature of your Keystone Cougar basically is a narrower nose that allows better clearance with short bed trucks. But since your truck bed is 5-1/2 feet you still would need a Sidewinder as the added clearance is not going to be quite enough. Your trailer should have a Lippert 1621 pin box so the correct Sidewinder would be the part # RP61420. I'd still recommend verifying the pin box since you didn't mention the model of your Cougar. For a fifth wheel hitch you'd...

  • Will a Curt E16 5th Wheel Hitch Work with Reese Quick-Install Custom Installation Kits
  • Yes, the Curt E16 5th Wheel Trailer Hitch part # C16115 will work with the Reese Quick-Install Custom Installation Kit w/ Base Rails part # RP50142-58. The Reese install kit will give you what is referred to as industry standard above bed base rails which works with most above bed mounted 5th wheel hitches from Reese, Pro Series, Husky, Etc. The Curt E16 is a great starter hitch and when paired with the Reese install kit will give you everything that is required to hit the road. However,...

  • Recommended 5th Wheel Towing Setup for a 2017 Ram 1500 with a 5-1/2 foot Bed
  • Since your 2017 Dodge Ram 1500 has a box that is shorter than 6 feet you will actually need to go with a stationary 5th wheel hitch and then change the pin box on your trailer to a Sidewinder pin box. There are no sliding 5th wheel hitches that will allow you to make a 90 degree turn with a truck that has a box under 6 feet. The Sidewinder takes the pivot point on your towing setup and moves it from the king pin back 22 inches to the rotating pin box. We have a selection of Sidewinders...

This kits uses frame brackets that mount to existing holes in the frame. Then for a cost-effective 5th wheel hitch you can use the Pro Series 15K hitch # PS30093. For an in-bed wiring harness use part # 50-97-410. Sidewinders are selected based on the specific OEM pin box model on the trailer. The...

  • Sidewinder Pin Box Replacement Recommendation to Replace a Mor/Ryde SPB72-1621LD
  • Based on the part number you gave for your Mor/Ryde pin box it sounds like you have a pin box based on the Lippert 1621 pin box. Which then for the correct Sidewinder you would want the part # RP61420. Since your truck has a 5-1/2 foot bed the Sidewinder pin box is exactly what you need to give you the turning clearance you'll need.

  • Reese Fifth Wheel Hitch and Rail Kit to Tow 2017 Cougar Lite
  • As long as the trailer you plan to tow has a Sidewinder or Reese Revolution pin box installed on it the Reese fifth wheel rail kit part # RP50142-58 and the Reese hitch part # RP30047 will fit and work well. Since your truck bed is 5-1/2 feet in length the best way to get the needed turning clearance is one of the pivoting pin boxes I mentioned. Since you have a 5th Airborne it's possible it's a Sidewinder/5th Airborne but you'd need to verify this. Either way though since you have the...

  • Fifth Wheel Rail Kit Recommendation for 2014 Dodge Ram 1500
  • A rail kit from a 2500 series Ram truck will not fit a 1500 regardless of the year so you'll need an all new kit for your 2014 Ram 1500. For that you'd want a custom install kit as they install much quicker and easier than universal style kits. For that the Reese rail kit part # RP50142-58 would be a great option.

  • Is There An Under Bed 5th Wheel Mount Kit for a 2011 Ram 1500 with the 5-1/2 Foot Bed
  • I do have an option for you but they do not make an under bed mounting kit for your 2011 Ram 1500 with the 5-1/2' bed. 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.

  • Fifth Wheel Towing Setup Recommendation for 2017 Ram 1500 5-1/2 Foot Bed
  • For trucks like your 2017 Ram 1500 with the 5-1/2 bed there's really only one hitch that will allow you enough turning clearance. For that you'd need the Demco Hijacker 13k auto slide part # DM8550040 which will automatically slide back 22-1/2 inches as you make tight turns. Then for the rail kit custom fit for your Ram you'd want the part # RP50142-58 which fits even if the truck has air suspension which normally is an issue.

  • Reese Fifth Wheel Rail Kit Recommendation for a 2015 Ram 1500 Short Bed
  • The fifth wheel rail kit I can recommend for your 2015 Ram 1500 is the part # RP50142-58 that you referenced that is a 10 bolt rail kit. Most manufacturers are going away from the 4 bolt rails and sticking with the 10 bolt rails since they feel the 10 bolt rails are more secure. With that being said, we do offer a 4 bolt kit, part # DM8552030-71 that has been confirmed as a fit for your vehicle.

  • Recommended 5th Wheel Hitch 2015 Dodge Ram 1500 with Short Bed
  • The best complete system I can recommend for your 2015 Ram 1500 with 5-1/2 foot bed, would be the Demco Hijacker Autoslide, # DM8550040. This hitch slides automatically while you drive to give you 22-1/2 inches of additional clearance for tight turns. It's design relieves you from getting into and out of the truck to operate a manual slider. It has a built in roller-and-guide assembly that allows for smooth, controlled, and automatic movement. This hitch would be paired with the Demco...

  • 5th Wheel Installation Kit Recommendation for 2010 Dodge Ram 1500 with 6 Ft Bed
  • When it comes to a kit to install your Reese 5th wheel on your 2010 Dodge Ram 1500 with 6 ft bed, I recommend the Reese Quick Install Custom Base Rails and Installation Kit # RP50142-58. A custom kit is going to reduce the amount of drilling and really cuts down the installation time. Both kits include all parts needed for installation; base rails, brackets, and hardware. I have attached the installation instructions for both kits.

  • Yes, it's possible to pull a fifth wheel using your 2014 Ram 1500 short bed with RamBox. However, before you purchase anything you will want to take some measurements and make sure everything will work. For starters you'll need a trailer that has as Sidewinder or Revolution pin box. If you buy a trailer without one it's possible you can replace it. Check out the article I've attached to see if a specific pin box is compatible. You'll need the pin box number currently on the trailer....

  • If you don't already have rails, I recommend the Reese Custom Rails # RP50142-58 for your truck. Once you have rails, I recommend the Curt A20 5th Wheel Trailer Hitch - Dual Jaw - 20,000 lbs # C16140 which will fit with your rails. This hitch has interlocking jaws and a fully articulating torsion head for controlled coupling and a quiet stable ride. This hitch has an adjustment from 13 to 17 inches tall. This hitch will work well with a Sidewinder that is required for a 5-1/2 foot...

The instructions on the brackets # RP50142 included in that kit give the measurement from the rear edge of the bed to the back of the rear rail of 28-15/16 inches and then you will have a measurement of 27-3/4 inches for a grand total of 56-11/16 inches from the rear lip of the bed not the tail gate.

You'd only need to drill through the bed of the truck.

This is comfortably under the truck's limits and you should not have any issues, especially since you only plan on going on a couple trips a year. I just recommend verifying the truck's towing capacity in your copy of the owners manual. If your Ram has a 6-1/2 foot bed, you will want to go with a sliding fifth wheel hitch if you do not have one already....
