Roadmaster Base Plates - RM-521447-4

  • Roadmaster
  • Removable Drawbars
  • Twist Lock Attachment

Roadmaster's crossbar-style brackets have a low profile and are virtually invisible. Each arm is easy to mount and simple to remove. Brackets install on your vehicle's frame to provide attachment points for your tow bar.


Features:

  • Hidden bracket design provides improved aesthetics compared with standard brackets
    • Crossbar-style brackets sit far back for a supremely clean look
  • 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 and car-mounted tow bars
  • Instructions and mounting hardware included
  • Made in the USA
  • Limited Lifetime Warranty


The drawbars, or front arms, on the crossbar-style 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.

Went on fairly easy with the help of your video to guide me. They look very nice on my 2017 Jeep Cherokee. I drilled 2 1/4in holes in each plate instead of cutting off the alignment tabs and small bolts. It took me awhile to get front end back on as I had to do a lot of modification to baffle. 471436

Review from a similar EZ4 in Base Plates


I purchased this EZ4 base plate to work in conjunction with the Falcon2 tow bar. It fit perfectly on my Wrangler Unlimited, and is tucked mostly out of site when not used. The two baseplate arms bolted to the cross bar of the Falcon2 are easily removed and stored away when not in use. Installation because of the weight and tight fit to the Wrangler frame, was found to be much easier with two people. 554274

Review from a similar EZ4 in Base Plates


I installed the trailer hitch first and it was quite simple, total time about 1 hour. Next I installed the EZ4 base plate kit on our 2017 GMC Terrain, a little bit more difficult, but the step by step video made the whole process much simpler, in fact, I kept my laptop in the garage while I was doing the installation and stopped/started as it did the work. I can't thank you enough for the video clips, they are a tremendous help. We will be leaving in a week or so, can't wait to try it out. 515670

Review from a similar EZ4 in Base Plates


This is the adapter kit i needed for my 2019 Jeep Cherokee to flat tow it behind my Class A Motorhome. At the time I first ordered this kit the factory still had to finish the design process as we had purchased the Jeep when it came out in 2018. It took about 6 weeks for the factory to call me to say it was done and could be ordered. My RV mechanic installed it and it went very well according to him. I towed the Jeep this weekend and it worked flawlessly. It replaces the tow hooks on the front of the Jeep. Everything arrived very quickly and in perfect order from etrailer. 694234

Review from a similar EZ4 in Base Plates


Great product for my 2014 Wrangler. Good materials, solid attachment to vehicle, and looks good. The e trailer installation video was great for assisting installation. Made the install much quicker and easier. The most difficult procedure for me was disconnecting the wiring harness on the back of the bumper. An old tack puller (or tool of similar design) would have been great for leveraging the pins out of their holes. Cutting the air dam was a slow process to ensure I didn't cut too much. A paper template to mark where to cut the air dam would make this process much simpler. Again, I can't emphasize enough how great the installation video was for making the steps easier. 126011

Very Happy! The shipping was fast; 3 days, including Thanks Giving. I was able to instal the base plat myself, just following the installation video on their web site. I watched it a couple of times while I was waiting for delivery, and then followed it step by step during installation. I wouldn't have dared attempt it myself without the video. I also installed the Tail Light Wiring Kit with Bulbs-RM-155 using the same method. Everything went without a problem. I will be buying from eTrailer again. 588968

Review from a similar EZ4 in Base Plates


The units went on my Chevy truck great and they work well the only problem is I can't take off my tow bar unless I unbolt it from the base plates so I have to leave the unit on all the time. It would take 4 bolts to remove . Then I could unlock the base plates and turn them in order to remove them. 443465


Comments
The base plates they are working fine I dont remove them they stay on all the time it has been 2 years now the tow bar that I use is bolted on so I would have to remove them to get the s out I should do this some time so they dont rust in place but real nice right now .

Installed it myself on a 2017 Ford Focus. Watched a few videos on how to pull front bumper and install mount. The hardest part was making the holes in the steel front bumper. I like the fact I can remove the outside mounts that the hitch mounts to. I’ve pulled the car about 5,000 miles behind the rv with no problems. 698216

Review from a similar EZ4 in Base Plates


The Base Plates are performing as expected, unfortunately chipping paint has plagued these Base Plates. This chipping paint has occurred along both of the leading edge of where the tow bar mounts. This has not been caused from abuse/misuse, it started happening soon after began using. Should not have happened so soon. 710582

  • Parts Needed to Flat Tow a 2016 Jeep Cherokee Behind a Motor Home
    It does not appear that you have to full fuses on your 2016 Jeep Cherokee to flat tow it behind a motor home. I recommend looking in the recreational towing section of the Jeep owner's manual to confirm. This information is for the Cherokee, not the Grand Cherokee. If the Cherokee is a Latitude or Limited model I recommend Roadmaster base plates # RM-521447-4. If it is a Trailhawk model I recommend # RM-521446-4.

  • Base Plate Cover Recommendation for a Roadmaster EZ4 Base Plate Kit
    To determine what the correct base plate cover would be for your EZ4 Base Plate kit part # RM-521447-4 you will need to measure the inner diameter of the tube of the base plate kit. If it measures 1-1/2 inches you would want the part # RM-210. If it measures 1-1/4 inches you would want part # RM-212. Both of these covers are solid black.

  • What Does Tow Bar and Base Plate Kit Typically Weigh of Flat Towing Setup
    Base plate kits like the # RM-521447-4 weigh around 40 lbs and tow bars like the # RM-501 weigh around 55 lbs. In general the weight of flat towing equipment doesn't need to be factored into the capacity of anything. Only thing you really need to make sure is that your tow vehicle has the towing capacity for the weight of your towed vehicle and you'd be set.
