Roadmaster Base Plates - RM-521440-5

  • 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.


Features:

  • 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 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.

2022 Jeep Cherokee

Was delivered quickly and I was able to install the baseplate assembly relatively easily after having watched a few of the etrailer videos. I did watch multiple different videos as my 2022 Grand Cherokee WK had slight variations from the videos. I did not have previous experience doing this type of automotive work so I will admit to some trepidation along the way but all ended perfectly. My wife was not too happy about me taking the bumper off of her new car with just 100 miles on it but she has regrouped. The only thing I used the written instructions for was to get the parts all organized and to get the correct torque for the bolts

I uses this base plate set up with the Roadmaster nighhawk tow bar. It was easy to install and easy to connect to the tow bar. No issues or complaints after the first year of use.

Works very well. Easy to use. This Jeep had OEM chrome tow hooks that had to be removed. Didn’t care for the look of the bare faceplate; So fabricated chrome hook fixtures that fit into the blank face plate when not towing.

This was an easy install for the bracket attaching to my Grand Cherokee. To be fair it took about 10 hours but this is including the wiring for the lights and I was pretty anal about the routings making extra sure of no pinching points, etc. This was my first time ever doing such. Instructions are good and you need to take your time. This is a high quality product that I would recommend to a friend. I used my Armada to do a test tow to make sure everything worked properly. Thumbs up on the test drive.

Well so far the base plate has been received and packaging was excellent as was speed of shipment. I have not yet put it on the Grand Cherokee - a bit too much snow. So as soon I complete that job I'll do a follow up post with some pictures.

  • Roadmaster Base Plate Compatibility with Tracker Tow Bar for 2014 Jeep Grand Cherokee
    The Roadmaster Tracker Tow Bar, part # RM-020 isn't compatible with a direct connect tow bar like the # RM-521440-5 you had looked at. You'd instead need to use a crossbar style base plate kit like # RM-521440-4. In addition to the base plates and tow bar, you'll also need a wiring solution, safety cables, and a supplemental braking system. I've linked to an FAQ article that lists suggested packages for flat towing your 2014 Jeep Grand Cherokee. I've also linked to an install video for...

I have even attached an install photo from Roadmaster on a model with the Summit trim package.

  • Will the Roadmaster Base Plate Kits Fit a 2015 Jeep Grand Cherokee Summit with Adaptive Cruise
    The Roadmaster Direct-Connect Base Plate Kit part # RM-521440-5 will work just fine with the adaptive cruise control (ACC) feature on your 2015 Jeep Grand Cherokee Summit as the brackets don't interfere with the sensor locations. There were issues with previous versions of the Roadmaster Direct-Connect Base Plate Kit on models with the adaptive cruise control (ACC) feature but that is no longer an issue.

  • Differences Between EZ4 and EZ5 Base Plate Kits for 2011 Jeep Grand Cherokee Overland
    For your 2011 (or 2012) Jeep Grand Cherokee there are two base plate options. You have the EZ4 kit part # RM-521440-4 and the EZ5 part # RM-521440-5. There isn't a standard EZ kit that's a fit. The primary difference between the two designs is the way they attach to the tow bar. The EZ5 does not use the quick-connect crossbar which provides a cleaner look, but prevents you from using some accessories that mount to the crossbar such as a Rock Guard like the Roadmaster # RM-4000.

  • Roadmaster Base Plate Kit Recommendation 2013 Jeep Grand Cherokee to Use Nighthawk Tow Bar
    The base plate kit part # RM-521440-4 does not come with a crossbar as it's the tow bar that would include this component. Since you are wanting to use the Nighthawk tow bar part # RM-676 you'd instead want the direct connect base plate from Roadmaster that fits your vehicle part # RM-521440-5 which attaches directly to the Nighthawk. I attached an install video for the base plate kit on a similar 2019 Grand Cherokee as well.

Since you're using a Roadmaster BlackHawk 2 All Terrain, Non-Binding Tow Bar - Motorhome Mount - 2" Hitch - 10K Item # RM-422 you can use either base plate with no adapters needed.

  • Can Roadmaster Crossbar Style Base Plates for a 2011 Jeep Grand Cherokee Be Purchased Without Arms
    I do have an option for you but base plate kits are offered as complete units only. That said, this would be a great time to upgrade to the direct connect style which does not require the bulky crossbar. The Roadmaster Direct-Connect Base Plate Kit part # RM-521440-5 will be a great option for you and will work well with the Roadmaster BlackHawk 2 All Terrain Tow Bar part # RM-422.

  • Recommended Base Plate Kit to Flat Tow a 2014 Jeep Grand Cherokee Overland
    Since you already have a Falcon tow bar I recommend going with Roadmaster base plates. You're correct that the old ones from your 2000 Jeep aren't going to fit. Both the EZ4 # RM-521440-4 and EZ5 # RM-521440-5 kits will work on your 2014 Jeep Grand Cherokee Overland. The biggest difference between the two is that the EZ5 doesn't need the Falcon's crossbar when you hook up. If you also need wiring for the Jeep's lights and a braking system I recommend the diode kit for the lights, part...

  • Can Older MX Bars be Matched to New Style Base Plate Kit for a 2017 Jeep Grand Cherokee
    Since the Roadmaster arms that you currently have are from the older MX style 1428-3 base plate kit you will need to purchase and entirely new base plate kit for your 2017 Jeep Grand Cherokee because the MX used a square tube for the arms but all of the new kits use a round tube. The equivalent of the MX style for your 2017 Grand Cherokee is the Direct-Connect Base Plate Kit # RM-521440-5. This will pair up directly with your Roadmaster Falcon All Terrain Tow Bar # RM-522.

  • Best Braking System for Flat Towing 2015 Jeep Wrangler Unlimited with 2015 Tiffin Allegro Bus 45
    The best supplemental braking system for your 2015 Jeep Wrangler Unlimited that works with the air brakes from your 2015 Tiffin Allegro Bus 45 is the SMI Air Force One # SM99243. This is a proportional braking system which means the brakes on your Jeep will apply at the same time and with the same intensity as the brakes on your Allegro plus it is a permanent installation that installs out of the way so you won't even realize it is still there when you aren't flat towing your Jeep.

  • Troubleshooting Non-Functioning Brake Lights When Flat Towing A 2012 Jeep Grand Cherokee
    The first thing to ensure is that the transfer case is in Neutral and that the transmission is in park. If not then you can damage the components of your 2012 Jeep Grand Cherokee. As for the wiring I recommend using a circuit tester like # PTW2993 to first test the functions on the trailer connector at the rear of the RV. Check to make sure all of the needed functions are providing a circuit, particularly the stop light function. If the signal is coming through from the motorhome then...

  • Recommended Supplemental Braking System for Flat Towing 2014 Jeep Grand Cherokee Behind RV
    Since your 2015 Tiffin has air brakes you want a system designed for them. Braking systems for hydraulic brakes can sometimes cause false braking on a toad vehicle if the motorhome towing it has air brakes so I recommend the Air Force One system # SM99243. I've linked an install video on a 2015 Jeep Grand Cherokee which will be the same process as your 2014. In addition to the braking system, you'll need some other items to safely flat tow the vehicle.
