Roadmaster Base Plates - RM-521447-5

  • Removable Drawbars
  • Roadmaster
  • Twist Lock Attachment

Designed for use with motor-home-mounted tow bars, the direct-connect brackets are virtually invisible, easy to mount and remove, and they eliminate the need for a quick-disconnect crossbar on your tow bar. Installs on your vehicle's frame.


  • Direct-connect brackets provide attachment points for your motor-home-mounted tow bar
  • Streamlined design creates supremely clean look
    • No obtrusive quick-disconnect crossbar
    • Hidden brackets sit even farther back than standard brackets
  • Drawbars attach and remove quickly and easily
    • Arms click to lock in place in brackets
    • Built-in pull rings let you unlock arms so you can twist and remove them
  • Computer-cut, all-steel construction provides exceptional strength
  • Black powder coat finish is durable and corrosion resistant
  • Simple installation - no welding required
    • Custom base plates ensure a perfect fit for your vehicle
  • Compatible with Roadmaster motor-home-mounted tow bars only
  • Instructions and mounting hardware included
  • Made in the USA
  • Limited Lifetime Warranty

Note: Roadmaster direct-connect base plates will only work with Roadmaster tow bars that slide into a trailer hitch, such as the Nighthawk, Sterling, Blackhawk, Blackhawk 2, Falcon, or Falcon 2. These base plates will not work with tow bars that require a hitch ball.

The drawbars, or front arms, on this base plate kit are supremely easy to mount and remove. Just insert them into the brackets and twist to lock them in place. To remove each arm, simply tug the built-in pull pin to disengage the lock, twist the arm back and pull it out of the bracket. Once the drawbars have been removed, the remaining brackets are virtually invisible. On most automobiles, the brackets are mounted within the grille, where they remain not only unseen, but protected from scrapes and scuffs as well.

This base plate kit is excellent. The install was easy. I like the removable arms because you can remove them when not needed. The RM-521447-5 was a great fit for my 2017 Jeep Cherokee Latitude 4 wheel drive.


Bolted directly to Grand Cherokee installation was easy. Same goes with hooking up my car to tow bar.



Still working as it was new.

2014 Jeep Cherokee

The install was pretty straightforward on my 2014 Jeep Cherokee Latitude. I found a youtube video on how to remove the front bumper. The only issue is how much grill to cut to allow the base plates to poke through. You have to cut way more than indicated in the instructions.

Jeep Cherokee

Had it installed by my RV Service guy, and it’s worked great for us in towing our Jeep Cherokee with the Roadmaster Falcon 2 towing system!

2017 Jeep Cherokee

This product was this is difficult installing because the instructions were hard to follow and understand in parts.


Meet/exceeded expectations. Informative, helpful, prompt.


Very good


Very efficient and much appreciated the quick ship.



I bought and self installed this on my 2021 GMC Sierra Duramax 1 year ago. Install took about 5 hours and wasn't difficult...I could problty install it in 2-3 hours after leaening the tricks. Weve towed the truck all over the USA since then (over 10,0000 miles) and it works great! I've used other brands and highly recommend Roadmaster tow systems over the competition.


Installed on my 2020 Jeep Cherokee for flat towing behind our motorhome . I wanted a tow bar connection that integrated with the front end of the Jeep and the removable arms did the trick . I had one issue with the driver side receiver bracket not lining up with the upper mount bolt hole on the Jeep, image 0547. Had to make a slight adjustment to the receiver bracket so the holes would line up, image 0551 and image 0559. The rest of the install went smoothly
I also installed the Demco braking Stay n Play Duo system , image 0565 which went in without any issues, image 6028. 7 thousand miles of towing later, couldn't be happier with the products


This is a rock solid baseplate. Installed on a 2023 Equinox LT (AWD). I followed etrailer's videos for installation and they are spot on. We connect with a Roadmaster Nighthawk tow bar, charge line kit, smart diode lighting kit, and a Demco Stay-in-Play supplimental braking system. It is fairly well hidden when not in-use. This setup is great!


I installed them on my new RAM 1500. Works great, very heavy duty. I also modified and attached a push bumper and used the Roadmaster base plates.


Installed on my 2020 jeep jl sport s with factory plastic bumper and plastic rock guard. Shane’s video was very helpful but I did not like how the metal plate behind the rock guard was cut away and how the rock guard had two big cut outs so I did some modifications. I cut two slots in the metal bracket and added angle brackets for extra support. As a result i did not use the supplied brackets for the rock guard. I created a template for the rock guard which resulted in two small cut outs. A lot of extra time but i am retired so time is relative. I think it looks great.


Installing on 2020 Jeep Trailhawk :

Pic #0557 : Roadmaster Base Plate Kit , Demco Supplemental Braking System , Diode Wiring Kit , Demco Battery Charge Wire Kit

Pic # 0548 ,0551 , 0559 Had to adjust the bracket plate to line up with the upper bolt holes

Pic #6028 finished install , mounted the operating unit to the top fuse box cover using automotive Velcro . Air cylinder , controller and LED light installed . Aside from the base plate bracket not lining up with the upper bolt holes I would give it 4 stars . My son in law is a master at solving mechanical issues .


Exactly what I needed. Written jbstructuons were spot on and video was very helpful.


I bought this base plate kit for my 2022 Jeep Rubicon Gladiator so I could flat tow behind my class a motor home with a Roadmaster Falcon all terrain non binding tow bar. The instructions were easy to follow and went smoothly except drilling the holes. That was my fault because I was using a dull drill bit. See attached photo


This kit worked out great for my 2022 Chevy Equinox. I like how it has separate side plates, which make it easier to attach the main bar. The points where it attaches to the frame seem plenty secure. It is important to watch the videos provided by etrailer as Ryan is very thorough and has good tips for installing. I would also recommend installing additional wiring while having the front end off. Overall, I was able to complete in my driveway. The hardest part was sorting out the wiring for whatever braking and tail lights you decide on. William S helped me pick all the necessary components needed for flat towing behind my Jayco RV. I am looking forward to a summer of camping and having more freedom to explore the area, now having a car.


The bracket kit fit my 2023 Subaru Crosstrek perfectly. The instructions are excellent and the video is really useful too. I’m really pleased with this RoadMaster bracket kit and the support from eTrailer.


The base plate arrived on time, with excellent instructions. I went slowly because my truck is only days old and still had it done in an evening.


Just took the maiden voyage with the new Motorhome and the new Tow Car or ( Toad ). After getting everything set up and installed on the coach and the dingy towing was a breeze. Hardly even noticed that i was towing a car behind me. Bought all RoadMaster equipment and purchased everything from etrailer, baseplate and towbar with the invisibrake system and all the necessary cables. Etrailer was Awesome they made sure that I had everything needed and that everything fit my vehicle.


Easiest I drive done. Works perfectly. I had some concerns if it would work on my Shelby F-150. etrailer put me in touch with Roadmaster directly who had never done one either. Said if it didn’t work I could return it. It fit with minor adjustments. Have towed a few thousand miles already. Couldn’t be happier


Have enjoyed the Roadmaster base plate on my Mercedes Benz Sprinter Van. The only complaint I had was what was required to install it. I have installed several in different vehicles and this one was the most difficult. Some are easier than others, but once installed, it performs as expected.

  • How to Disable the Auto Park Brake for Flat-Towing on a 2018 Jeep Cherokee
    According to the owner's manual for your 2018 Jeep Cherokee, "You must ensure that the Auto Park Brake feature is disabled before towing this vehicle, to avoid inadvertent Electric Park Brake engagement. The Auto Park Brake feature is enabled or disabled via the customer programmable features in the Uconnect Settings". Therefore, I recommend disabling the Auto Park Brake though the Uconnect settings and not by pulling the fuse. In order to flat-tow the vehicle you are going to need a base...

  • Fit of the Falcon 2 Towbar to the Roadmaster Baseplate part # RM-521447-5
    You are in great shape. It is typical to have a little room on each side of the tow bar connections. There will be zero negative effect from this as it is by design.

  • Does 2018 Jeep Cherokee Require Mopar Wiring Kit 68321424AB for Flat Towing
    Yes, the Mopar flat-tow wiring kit 68321424AB is required to keep your 2018 Jeep Cherokee from death wobble if you flat tow. This can be acquired through your local Chrysler or Jeep dealership, and I would try to press them to handle it all for you since your vehicle is marketed as flat-towable as-is. We all know how dealerships are though, so if they won't install it for free I've read that it's fairly easy to install especially if you're a normal DIYer. I'm linking a guide on parts to...

  • Adapter Needed to Tow Vehicle with Roadmaster EZ5 Base Plate Kit and Blue Ox Tow Bar
    To use a Roadmaster EZ5 base plate like part # RM-521447-5 with a Blue Ox Ascent tow bar you'd just need the adapter part # BX88185 and you'd be set. You would not need to swap the pins either.

  • Does Fuse Need to be Removed When Not Towing a 2018 Jeep Cherokee
    I do have a solution for you but since we don't carry or install Mopar parts I wouldn't be able to tell you if the service tech you spoke with knew what they were talking about or not. Typically a fuse is pulled to keep the battery from draining. I am not sure why a fuse would need to be removed when your 2018 Jeep Cherokee is not being towed though. If your fuse does need to be removed each time you are done towing your Jeep then I recommend installing a few bypass switch like the Blue...

  • Fixing The Death Wobble While Flat Towing A 2018 Jeep Cherokee Trailhawk
    Newer model Jeeps have electric power steering systems that require activation while flat towing to prevent the death wobble. You'll have to purchase the Mopar Recreational Flat Tow Wiring Kit part 68321424AB through a dealer to activate the power steering and resolve the death wobble. Activating the electric power steering will put a drain on your vehicle's battery so you'll also want the BrakeBuddy Towed Vehicle Battery Charge Kit Item # BB54FR maintain the charge level of your battery.

  • Which Roadmaster Base Plate Kit for 2017 Jeep Cherokee Limited
    For your 2017 Jeep Cherokee both the EZ4 base plate part # RM-521447-4 and the EZ5 part # RM-521447-5 are a fit for the vehicle and would work well with the Falcon 2 tow bar part # RM-520. If it were me I would go with the EZ5 since it doesn't require you to use the crossbar and will be a bit easier to use. For safety cables you can use # RM-643. The coiled design helps keep the cables off of the ground. For lighting you can use the diode kit, # RM-15267, and not have to worry about...

    So you definitely have a Roadmaster base plate kit on your 2015 Jeep Cherokee and the part # RM-ARMS is the correct part you'll need to get the replacement arms but we have to determine whether you have the part # RM-521447-5 or the # RM-521447-4. The way you'll be able to tell is to look closer to where the kit attaches to the front of the vehicle frame.

    I believe you are asking what gear should the transmission of your 2017 Jeep Cherokee be in when towing. You'd be fine to just leave the transmission in drive.

For trailer wiring you'd then want the Curt # C56208 which is a confirmed fit as well. Since you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with...

Unfortunately, that part must be sourced at a dealership as well. We do however, have everything else you may need to flat tow the Jeep.
