Roadmaster Base Plates - RM-524431-5

  • 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 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.

2018 Ford F-150

The installation of the Roadmaster Direct Connect Base Plate kit on my 2018 F150 with tow hooks was so far the easiest part of the conversion to making the F150 towable. It only took a couple of hours to complete, a few metric sockets, pry bar, toque wrench, drill and 1/2-inch dill bit is all the tools I needed, along with a helping hand from my wife to remove and replace the bumper.


Overall pretty straight forward install, hardest part was drilling the holes. Once installed it has worked great

2019 Ford F-150

Have done business with your company several times and have never been disappointed with the great service you provide. Thanks so much for your continued support of the RV world.


easy install and work like a charm
these are replacements after an accident with truck


Base plate came as promised.


Roadmaster equipment good. Using it as we speak


It was so easy to put on is unbelievable I thought it would I had a hard time but I didn’t want on YouTube to learn how to do it and everything was assess


The moment I received the base plate it took me 2. Hours to install peace of cake good instructions easy to follow extremely happy going on a trip next week thx etrailer job well done


Quick delivery!


Out flippin standing-Instruction video was great. Took all of 2 hours with a Crescent Wrench, Duct tape and a wooden stick (Kidding, I used actual tools). but it really did take 2 hours start to finish. Great quality product, arrived faster than expected. Very satisfied. and now I get to keep my beloved F150 with me everywhere I go :)

After a year and about 6000 miles I am just as happy. No issues and still works very well. Double checked the mounting and bolts and nothing has moved since the original install.

No issues after a year, quick and easy to install and remove the arms.

They work great and look good on the front of my truck. Checked the bolts that hold the bracket to the frame and all are tight

smartly blends in with truck and neatly appearance when not hitch as compliments from others roll in

2016 Ford Explorer

Bad experience with Roadmaster this time around! I have used their product for 15 years on my Ford Explorer towing behind a 40 foot diesel pusher with no issues. Purchased this set for my 2016 F-150 Limited pickup on line from etrailer and the fit from Roadmaster was terrible!!! the passenger side slide in arm when locked in place with the receiver installed on the vehicle, made the horizontal female cocked to about 25 degrees up from a horizontal plane!!! this meant the arm from my $1200.00 Roadmaster tow arm would not hook up. I had to take to a weld shop to make repairs on the arm to set it in a horizontal position!!! Roadmaster would not believe this was possible to their product said they had only seen this happen once before? It happened before but now you don't believe ME?


Wiring kit and tow brackets showed up on time. Robert was very helpful on the phone. I've also ordered from etrailer many times good company. Install wet very well. Their videos help also sometimes easier than reading directions. Quality of the hardware and base plates and removable arms are well-made.

2018 Ford F-150

Product was very well built and was easily installed with two people. For my 2018 ford f150 I used the direct connect removable arms Rm- 524431-5 and added a cross bar for better stability. e-trailer sales the RM-524431-4 that has the cross bar for the same price. (My mistake and the truck towed better with a Cross bar)



The base plates are working great. The only problem is that I dont get to use them enough. I towed about 3,000 miles since my purchase and have had no issues at all.
Cary N - 04/05/2019

2016 GMC Canyon

I've been towing a vehicle behind my motor home for the last 12 years. That includes four trucks and one car. Each time I've used Roadmaster Base Plates and a Roadmaster tow bar. I find that when I'm outfitting a new truck for towing, etrailer always has the parts I need (base plates and taillight wiring) at the best prices with the quickest shipping.


Takes a little muscle to properly install, but once installed it works like a charm.


excellent product. works great. top quality material. highly recommend.

2013 Chevrolet Sonic

Packaging was really well done and held up during the shipment.
The quality appears to be great.


These were very easy to install. Basically plug and play so to speak. Joining up my Bricker to my RV is very easy, one person operation. Great product.


After pulling my pickup for the first time, the front bolt of the bracket sheared off.
Had to go in a change the bolts to grade 8 bolts. So far everything has been working fine while pulling my pickup.


Very easy to install. It is working gre at

2018 Ford F-150

Received yesterday, quality looks great; have installed one side. Instructions are fairly good but totally lacking on removal of the 2018 F150 bumper. Access to the bolts inside the frame on the 2018 is very good so used grade 8 nylock nuts instead of the included wire held nuts. Access to hold the full size hex nuts is very good so it was easier to hold the nuts while torquing.


Done deal, I think!

  • Need Flat-Towing Set-Up to Pull 2013 Ford F-150 SVT Raptor Behind 2013 Southwind Motor Home
    The 2013 Ford F-150 SVT Raptor with 6.2L V8 and 6R80 transmission can usually be flat-towed without modifications but your owners manual should be consulted to confirm the capabilities of your specific truck. The dry weight of the Super Crew Cab version of your truck is 6113-lbs; the weight of the Super Cab version is 6004-lbs. Both weigh well in excess of the 5000-lb-rating of the hitch that you indicated is installed on your 2013 Fleetwood Southwind motor home. It is not recommended...

  • Will the Base Plates for a 2015 Ford F-150 Work With a Grille Guard
    The Roadmaster Direct-Connect Base Plate Kit part # RM-524431-5 is a great option for a 2015 Ford F-150 and a confirmed fit. It will mount using the factory tow hook holes so there's only minimal drilling required. In regards to compatibility with a grille guard or bull bar, this would vary by guard/bar but judging where most mount it would not be compatible with most setups. I can't recommend changing or modifying any of the hardware.

  • Is Roadmaster Base Plate Kit Available without Removable Arms
    The Roadmaster base plate kits like the part # RM-524431-5 are not available without the removable arms. Worth nothing is that rarely will the removable arms fit a different base plate kit since the two are made together and the tolerances are so tight.

    The Roadmaster EZ5 Base Plate Kit - Removable Arms # RM-524431-5 will fit your 2017 Ford F-150 and your Falcon Tow Bar, however they will not work with your Rock Shield. For baseplates that will work with your Rock Shield, I recommend the Roadmaster EZ4 Base Plate Kit - Removable Arms # RM-524431-4.

  • Can Roadmaster Direct-Connect Base Plate Kit RM-524431-5 Be Used with Sterling All Terrain Tow Bar
    Yes, the Roadmaster Direct-Connect Base Plate Kit # RM-524431-5 on your 2018 Ford F-150 will work perfectly with the Roadmaster Sterling All Terrain Tow Bar # RM-576. You are correct that when hooking up to the base plate arms you will remove the crossbar on the Sterling All Terrain, as the tow bar arms will hook up directly to the Roadmaster base plates. This does allow for a much simpler hookup process. You can simply keep the quick-disconnect crossbar in storage in case you ever need...

  • Can Base Plates Be Installed on 2016 Ford F-150 That Has Grille Guard
    We certainly have base plate kits available for your 2016 Ford F-150 that will hook right up to your existing Sterling All Terrain Tow Bar # RM-576, but they will all require that you first remove the Ranch Grill Guard that you have mounted. This will be the case with any base plate kit as they simply require the same mounting space as the guard. For the base plates I recommend the Roadmaster Direct-Connect # RM-524431-5 that features removable drawbars and a streamlined design that lets...

  • High Low Adapter for 5-1/2 inch Coach/Toad Height Difference
    A 4 inch high-low adapter would be correct for a tow bar/base plate height difference of 5-1/2 inches since you basically just have to get within 3 inches of level. So for that the Roadmaster part # RM-048-4 would work great as it is the correct rise/drop and has a 10,000 lb total weight capacity.

  • Difference Between Crossbar Style Baseplate and Direct Connect Baseplate Towing 2019 Ford F-150
    The main difference between the Roadmaster Crossbar Style Baseplate # RM-524431-4 and the Roadmaster Direct Connect Baseplate # RM-524431-5 comes down to the ease of installation of the tow bars; typically vehicles that require some extra stability will only have the crossbar style available. Crossbar style tow bars are traditionally going to be much heavier and more difficult to install on the tow vehicle than the direct connects, but once you're pulling I don't think you'll notice a considerable...

  • Can the Sterling Tow Bar Safety Cables be Used with Roadmaster EZ5 Base Plates
    There is a way to use the safety cables that come with the Sterling tow bar # RM-576 with Roadmaster EZ5 base plates such as # RM-524431-5 for the 2017 Ford F-150. The Sterling cable anchors must be attached to the frame of the towed vehicle or welded to the receiver portion of the base plate brackets. A professional welder could perform this task for a nominal fee. The other option is to not use the included cables and instead use separate coiled cables such as # RM-653.

    According to Roadmaster, their # RM-524431-5 base plate kit only works on Lariat models with the 6.2L engine. For your 5.0 equipped Lariat, you'd want to use the # 495-3A base plate kit. This base plate kit is compatible with hitch mounted (not coupler mounted) Roadmaster tow bars like the # RM-576 Sterling Tow Bar.
