Is this right for you? Product Expert Kathleen M says:

Yes, if you:

  • Like being able to back-up to your king pin and hook up without having to get out to open and close the jaws each time
  • Tow with a dually truck or aren't super tall and like having a longer handle to make it easier to throw open the jaws
  • Have a pin box that doesn't extend down very far and need a hitch that sits almost even with your bed rails

No, if you:

  • Use a tonneau cover often and want to be able to close it without having to take out the hitch
  • Prefer the most overbuilt option available, even if it's more hitch than you really need
  • Don't want to do the extra work needed to clear out paint in bolt holes and threads

Forged, Self-Latching Jaw

Self-Latching Jaw

The one-piece jaw on this fifth-wheel hitch provides absolute security with its wraparound design. Increased jaw-to-king-pin contact results in not only a stronger connection, but less noisy rattling and stiff chucking as well.

The jaw is also always ready to receive, so you don't need to use the handle to open it before backing up toward your trailer. As long as the bail pin is removed from the latching handle, the jaw will accept the king pin as it enters the hitch.

Finally, the jaw is self-latching, so it will automatically secure your trailer's king pin when it moves into the jaw.

Quiet, Comfortable Ride

Pivot Bushings

In addition to the tight jaw tolerance, a close connection between the head and the pivot bushings further reduces rattle and movement. And because the pivot bushings are independent from the head, they can be tightened to ensure a strong connection over time.

King Pin Indicator Prevents High Pinning

King Pin Indicator

This M5 hitch features a built-in king pin indicator to ensure proper hookup. This indicator is located on the back of the head along with a V-shaped notch that are both visible from the cab of your truck. The V-notch is lined up with the jaw at the front of the hitch, and can be used as a guiding point to line the king pin up with the jaw as you back up your truck. The jaw also has an internal plate that keeps the king pin from entering if it is too high to enter safely. As a result, the king pin indicator will only change from red to green if the king pin is fully engaged in the jaw.

Easy-to-Use Latching Handle

Lever and Hitch

This hitch's handle is designed for smooth motion and effortless operation. It requires only 2 fingers to use and won't bind up as you pull. In addition, the handle is long, so it's easy to access from outside of your truck bed. And the ergonomic grip makes it comfortable to hold and pull from different angles.

Installed in a 2018 GMC 3500 LB SRW

it was really easy to put together. Its light enough move in and out and very sturdy. I did not have a clearance issue with the Backflip cover regarding the stock handle. See pics.

Just a heads up, I had an issue with the threading in the legs, etrailer was very understanding and sent me out replacements supper fast. I contacted Reese regarding paint guncked up in the threading and they were aware of the issue, they recommended running a wire brush or a tap to clean it out.

One year later. No issues. I get complemens about how easy the hitch is to use, the ability to slide stuff under it, and how much room I still have in the bed with the hitch in. Would buy again.

2019 Chevrolet Silverado 3500

I recently purchased a Reese M5 20K hitch for my new Silverado 3500HD, Crew Cab, 8’ bed. As usual, Etrailer pricing was very good and with free shipping to boot. The hitch arrived via UPS in just a few days after placing the order.

Following the detailed instructions provided by Reese, the install into the factory “puck” system, was fairly straight forward. However, a word of caution concerning the install. There are 4 15/16” bolts that need to be torqued to 220-foot pounds and are somewhat difficult to get to. Fortunately, I was able to borrow a torque wrench that would accommodate the recommended foot pounds of torque.

Also, you may have an issue if you need to place the hitch at its highest position. The release handle might protrude above the bed rails of your truck in this position. This will be a problem if you have a bed cover. Reese is/was well aware of this issue and sells an after-market handle that will correct this issue. Etrailer lists this handle on their Web page.

Droppedsides into pucks, bolted center support on and pinned 5th wheel plate. 35 minutes max. Went to geogia and pulled 12,600lb new camper home. No issues at all. Would recommend lube disc keeps grease off when you remove hitch for storage.

2018 Chevrolet Silverado 3500

Wow what a great job you guys did! I received the new hitch on time an with all parts required to put it together.



I have the Reese M5 for the Chevy towing package and it works great. No unnecessary movement hooks up easy and fit like a glove. The hitch is a bit more complicated to install than you make sound with getting the prescribed 220’ lbs of torque required but we got and it works great. And thanks to Molly E for getting our order straight and here when we needed it.


Has been a great hitch with no issues and very easy to use. The single jaw gives me better confidence when the jaw is locked that it is truly secure. Recently returned from a 9000mi roundtrip from WA to FL with total confidence. Great product highly recommend and if needed will purchase again.


We have owned the 5th wheel hitch for a year now and absolutely love it! It has been everything we hoped it would be. Sturdy easy to use and would highly recommend it to anyone!

2018 GMC Sierra 3500

Shipping was quick , but was missing some hardware to assemble.

Thank you for bringing this to our attention. I will have our customer service team reach out to you.

Very well-built happy with the quality

2016 BMW M5

I ordered the Reese M5 hitch it showed up two days later free shipping. Fantastic thank you. I have not opened the package yet.



Your company was great. Don't care for this hitch, although I have owned many hitches in 35 years of towing. Very finicky and some parts are flimsy. I will likely replace the hitch this year and will gladly order from you again


Love the hitch. Just as I ordered. It was the first new hitch in almost 20 years. I really like no rails in truck bed and the color- coded hitched indicator. Also, this hitch is much quieter than my last one. Thanks Etrailer.


Overall I think it is a good product. The rubber hand grip didnt last 2 months before tearing off. Does not always connect on first try. Must be lined up near perfect for it to connect consistently.


The product seems to be first class as with the service, delivery and swift replacement of the damaged handle grip during shipping. Thx etrailer.


I don’t like it one bit.



Review from a similar M5 in Fifth Wheel Hitch

This would be a three but etrailer's customer service is excellent. Everyone I've dealt with has been exceptional.

Reese needs to get their act together. Three month backorder (okay COVID-19 has everyone backed up). Finally get the order and the release handle grip is destroyed, just crumbled almost like it was cooked. I have to adjust the pucks, which is expected, but Reese installed the Carter pins, which are a [beast] to remove in order to adjust the puck, suggestion Reese just leave them out for the installer to install. The the final [blow] from Reese on top of their otherwise great paint job, the bolt holes for the assembly are filled with paint, Reese howabout running a thread chase through these threads so the installer doesn't risk cross threading the bolt, it's just the small things that would make an otherwise outstanding hitch better.

Thanks for your words. Customer Service will reach out to you about the broken handle.

Review from a similar M5 in Fifth Wheel Hitch

We are so very pleased with our 27K hitch! The order process was easy and delivery was very fast. We have used a Reese hitch for years now. We just upgraded our fifth wheel RV and it wieghs in at 16K our old hitch was an 18K hitch so we were within 2K of max weight. We felt that that was too close so we went big, it feels (pulls) better and I feel more safe knowing that we have plenty of hitch. Thank you for such great products.
Jason and Patricia

The hitch is amazing, we have been pulling our 42 fifthwheel all over and its like it isnt even there. No pops or squeaks either. Very very pleased.

Review from a similar M5 in Fifth Wheel Hitch

Couldn’t be easier to use or more heavily built and secure. Only one issue. Though I didn’t have to change out bolts or use a tap and die set to put the base together, I would highly recommend having the correct tap and die available, just in case. From what I have read many people have had problems with these bolts/holes. I only had an issue with one, but it wasn’t fun. I don’t have a T and D available. Pretty sure it would have been a cinch if I had. ALSO, most people I know don’t have the correct type of torque wrench for the job. If you have to buy one it might be cheaper to have a trusted shop assemble the hitch. It’s pretty easy, but the wrench isn’t cheap, even if you buy an inexpensive (cheap) one. I rated 5 stars because I read all of the reviews and issues, bought with my eyes wide open, and was very happy to find that the bulk of the comparatively few negative reviews were either exaggerate, a QC issue that had been dealt with, or I just got plain lucky. I’ve had the hitch for 7months pull a 16,000 GVWR 5th wheel of my own and have pulled for friends.


Review from a similar M5 in Fifth Wheel Hitch

It's a little heavy but manageable for the average fellers. I pieced it together in the bed of my truck as it will be a permanent fixture and as the installation brochure pointed out. They did paint the threaded holes witch could make installation of bolts a little time consuming but with my 1/2" impact it was a breeze, also was the 220 fps of torque with a 4" extension and a torque wrench rental from auto zone witch is free.The castle nuts with the cutter pins were set right but one, removed the one as they did provide 4 extra. Took me about 45 minutes to assemble. Be sure to grease top plate so that thier is no bind. Very happy as this is my very first 5th wheel hitch install and hooks with ease and the green/red indicator is great,and tows nice.

Perfect fit, easy hook up, one thing though when you have this in a short bed pickup the 5th wheel rubs the corner of the cab a little but no biggie. I would definitely buy again and highly recommend.

Review from a similar M5 in Fifth Wheel Hitch

Tried to install this on a 2001 Chevy Silverado 3500, dual rear wheel, long bed, 4x4, diesel engine truck. The clamp style mounting simply does not work. The ONLY way I can see this working is by drilling added holes in the frame of the truck at the front end of the side plates. This is because of a bend in the frame at the clamp location. Also at this location the frame is boxed in and any bolt holes will be hidden. Bolts would have to fished in with bolt wires.

I see that you are stuck on some parts of this installation. I have gotten in contact with one of our technicians and they had mentioned that you should be able to find what you need in the instructions on page 5. https:www.reeseprod.comproduct-assetsinstallN30926.pdf

Review from a similar M5 in Fifth Wheel Hitch

The installation video was great and assembling the hitch went very well. I have a tonneau cover and it mentioned that you may need to place the handle upside down. I actually attached mine right side up and just tilted the hitch to that side and had plenty of space to close the cover.


Review from a similar M5 in Fifth Wheel Hitch

Just received yesterday, will be having it installed on Monday and will be pulling my new camper home next Saturday. Will update afterwards with pics

Still works good, but every once in a while it dosent want to latch around the kingpin.
Jeff - 10/09/2022


Review from a similar M5 in Fifth Wheel Hitch

Overall I’m happy with how the M5 functions. The assembly instructions were a little vague which meant I had to do it twice. I am disappointed in how the side accent panels are (were) attached. ALL the cheap little panel fasteners were broken and so I’m operating without them. I’ll keep the nylon spacers and use bolts instead of that plastic garbage. I would have sent it back if it were not for taking delivery of my camper the next day.

I have reached out to the manufacturer and they are shipping out new fasteners. I will email you the tracking information.

Review from a similar M5 in Fifth Wheel Hitch

I have used your product for many years and have always been very happy. On the installation and assembly I have the following comments. To qualify myself, I spent many years running facilities that builds equipment for distribution all over the world.

Someone needs to have a discussion with your assembly Supervisor and Technicians about installing the cotter pins on the crown nuts. They obviously KNOW they are going to have to be removed to adjust the BY HAND tightness that has to be done during the installation process because they send (4) extra cotter pins for replacement purposes. I would recommend that the assembler or technician bend the pin just enough to keep it in the CROWN NUT DURING SHIPPING with an explicit WARNING that states "FULLY SET COTTER PINS AFTER FINAL HAND TIGHTNING ADJUSTMENT". The way mine came in, It was a pure pain in the ass to get them out.... the technician had hammered them flat to the top of the bolt. If I were your company, I would be concerned about the people that did not adjust the puck clearance because of the pain in the ass it is to get the pins out. (I just happened to have all the tool to do this, I'm sure a lot of people don't). Apparently your QC department only spot checks the pull handles for fitment on the slide plate. I had to open mine up to make it fit. Also, you could use prevailing torque nuts for connecting this arm and do away with the lock washer. I would say the device is very good as it is now. It would be Fantastic with more thought given for the installer concerning the cotter pin issue. I have looked at many of the Ratings and it seems the cotter pin issue is the number 1 issue. The paint on the threads is common on everything that is powder coated. I hope this helps your company. Oh, I changed my rating to a 5 star because I really like the final product

  • Correct Reese M5 5th Wheel Trailer Hitch for 2018 GMC Sierra 3500
    The Reese M5 5th Wheel Trailer Hitch for Chevy/GMC Towing Prep Package part # RP30890 is an excellent option for a 2018 GMC Sierra 3500. It has a wrap-around jaw design which will grip the kingpin tightly therefore reducing the amount of slop which attributes to a rough tow. It also has a very wide funnel which is going to make coupling the trailer much easier. The hitch simply drops into the pucks in the truck bed and then all you'll need to do is turn the handles to lock it in place.

    There is an easy way to figure out how to determine what height setting a fifth wheel hitch such as the Reese M5 # RP30890 needs to be in your 2019 GMC Sierra 2500, just keep in mind you will need five to six inches of space from your Silverado's bed rails to your trailer as in the accompanying photo.

    When measuring the pin box height you'll need to have the trailer level and the measure from the ground to the base of the king pin (pictured below). I recommend rechecking this measurement yourself since the dealership probably has zero clue what they're doing.

  • Will Reese M5 20K for Puck System Fit Puck System on 2019 GMC Sierra 3500 Denali
    We do have 5th wheel hitches that are compatible with the puck system on your 2019 GMC Sierra 3500 Denali so to get your Reese M5 20K # RP30921, which is designed for Ford puck systems, compatible with your GMC puck system you'll have to swap out the legs with # RP30889. If you had to replace your whole hitch you would instead use the Reese M5 # RP30890 that fits with the puck system on your GMC Sierra. It has a single jaw but it is rated for a high capacity 20K, has an indicator for when...

  • Can Reese Signature Series 5th Wheel Hitch Fit Puck System on 2018 GMC Sierra 2500
    I do have a solution for you to tow your 5th wheel camper with your 2018 GMC Sierra 2500 but when I reached out to my contact at Reese he said that at this point in time (August 2019) they do not have a foot system for the Signature Series 5th wheel hitch to match the puck footprint for the GM pickups. The only hitch they currently have to offer for your puck system is the M5 which comes in a 20K # RP30890 or 27K # RP30895 capacity and is stationary so you won't want to use it for a short...

  • Which Sidewinder Wedge Should be Used with Reese M5 Fifth Wheel Hitch
    We have spoken with our contacts at Reese about this before and with the M5 Reese hitch part # RP30890 that you referenced they recommend using the shorter end of the universal wedge for Sidewinders # 201100 for your # RP24FR sidewinder. I attached a picture that shows this configuration as well.

  • Availability of Replacement Legs for Reese M5 20k Hitches that Fit GM Puck System
    The Reese M5 20k hitch part # RP30890 has the leg kit part # RP30889 as a replacement part. This would be correct if the GM truck was made between 2016 and 2019 since it changed in 2020. If instead you had the version of the M5 that fits the 2020 and newer trucks you'd need the legs # RP26FR instead. There isn't a way to adapt a hitch designed for above bed rails to fit the rail kit directly. Let me know what year truck you have though and I can let you know if there's a rail kit adapter...

  • Recommended 5th Wheel Hitch For 2017 GMC Seirra Denali 3500HD Dually With OEM Puck System
    For your 2017 GMC Sierra 3500 with 8' bed and OEM prep package, I recommend going with the Curt Q24 5th Wheel Trailer Hitch for Chevy/GMC Towing Prep Package # C16545-16025. This is a an excellent hitch that will simply lock into the factory puck system on your vehicle. It has an impressive gross towing weight of 24,000 lbs and max vertical load of 7,000 lbs. Another thing I really like is that is has 4" of height adjustment (13" - 17"), whereas a lot of 5th wheel hitches only have about...

  • Wedge for Reese M5 Fifth Wheel Hitch and Sidewinder in 2019 GMC Sierra 3500HD
    I spoke with a representative of Reese who said that the Reese M5 5th Wheel Trailer Hitch # RP30890 does not have a custom wedge. The Sidewinder # RP34FR comes with a universal wedge, part # 201100 that you will use with your hitch. This is a great set up you have chosen for you 2019 GMC Sierra 3500HD; the Reese M5 hitch will fit directly into the puck system of your truck and has a unique jaw system called a "Talon" which is a single-piece jaw that will wrap fully around your Sidewinder's...
