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.

  • 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.

The proportional breaking never worked right and on our last trip the system kept cutting out until it quit working all together. I was in the southern US and had to drive back to Canada without the aid of the breaking system. i tried to check it out and fix it but was unable to get continuous power to the brake buddy.


Just received my base plate and installed. Really satisfied about the look on my 2020 Ford F150.

2018 Ford F-150

Reliable information, excellent products, very quick service and delivery. I ordered multiple products to set up towing on vehicle for RV. Ordered Tuesday here on Friday! Excellent!


Perfect fit and high quality product


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


Fast delivery great service

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.

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?

2016 Ford F-150

Still working great after many miles towing my 2016 F150.

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.


Done deal, I think!

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.


Exactly what I was looking for to flat tow my raptor.


Great place to shop, in and out in no time. Thank you Alex.

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)


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


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.

2016 Ford F-150

Arrived quickly in perfect condition, install video will be very helpful. Thank you for the quick service!



Been down and back from fl. with the my MH, towing is solid as a rock, checked my nuts and bolts at the door, all tight and ready for a trip out to Wy. in August. Highly recommend these base plates and etrailer as the best source for them!


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.


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

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.


it fit great

Ford F-150

Working with etrailer has always been exceptional, and this was no exception. Working with Courtney was great, knew her stuff and help me make sure I got all the right parts so I could flat tow a 2020 F-150.

This is our second purchase of this product. We like the ease of installing and connecting to the RV. Can't wait to get it on the road to see how the new vehicle pulls down the road.

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.

Ford F-150

These have worked well. They were a bit of a challenge to install, but that was more about the F150 than the brackets.

  • Is There an Installation Video Available for Roadmaster Crossbar-Style Base Plate Kit # RM-524431-4
    You do not have to bolt and unbolt the drawbar every time. The tow bar disconnects from your truck but you can leave it installed on your motorhome when you are not towing your 2017 Ford F-150. You may want to consider a locking hitch pin to deter theft of your tow bar. I recommend the etrailer Hitch Receiver Lock for 2" and 2-1/2" Hitches - Flush - 3-5/8" Span - Chrome # e98881. We do need to verify your F-150 can be flat-towed, if it is a 4-wheel drive it can be flat-towed. If it is...

Since you already have the Blue Ox Patriot Braking System item # BLU37TR you may also need the Second Vehicle Breakaway Kit for Blue Ox Patriot Supplemental Braking Systems item # BRK2505 and definitely the 12 Volt Outlet Kit, 20 amps item # RM-9332 to power the Patriot.

  • Parts Needed For Flat Towing a 2020 Ford F-150
    First I recommend using the Roadmaster Direct-Connect Base Plate Kit # RM-524431-5 for your 2020 Ford F-150. I have found the Roadmaster parts to be the best quality over time. When this was installed on a truck with 275/55R20 tires the arms were 15-3/4" high. You will need to find the height of your motorhome receiver to determine if you need a High-Low Adapter like the 4" # RM-048-4 to keep the bars within 3" of level. If you need help confirming what you need for this please send me...

  • 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.

  • Confirming Flat Tow Components for 2019 Ford F-150 4x4
    You have done your homework for your 2019 Ford F-150 4x4. You can use either the Roadmaster EZ5 # RM-524431-5 base plates or the EZ4 # RM-524431-4. The difference is the EZ5 directly connect to the tow bar and the EZ4 will use a crossbar for connection. So specifically with the Nighthawk tow bar # RM-676, I recommend the EZ5 # RM-524431-5 because the crossbar doesn't come with that tow bar. This tow bar also comes with the umbilical cord and safety cables, so you won't need to get those...

  • Comparing Roadmaster And Blue Ox Flat Tow Components For 2020 Ford F-150
    I would be happy to recommend the parts needed to flat tow your new 2020 Ford F-150 behind your 2021 Winnebago Adventurer 29B but first you will need to confirm the weight of your F-150 as they can weight between 4090-5684lbs depending on which model you have. Since your Adventurer has a trailer hitch receiver rated for 5000lbs, if your F-150 exceeds that you will need to reach out to Winnebago to find out if there is a heavier duty trailer hitch receiver option for you.

  • 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...

  • Parts Needed to Flat Tow 2016 Ford F-150
    If your 2016 Ford F-150 is a 4WD model it's flat towable as-is. If it's a two wheel drive then you'd have to have a transmission lube pump installed. To flat tow it we carry basically everything you'd need minus a lube pump (if needed). For a base plate kit you'd want the Roadmaster part # RM-524431-5 which I attached an install video for. In addition to the base plates, you will also need a compatible tow bar, safety cables, lighting, and supplemental braking to flat tow your vehicle....

  • Flat Tow Set Up For A 2012 Ford F-150 Platinum EcoBoost 4x4 Super Crew
    I am happy to suggest a flat tow setup for your 2012 Ford F-150 Platinum EcoBoost 4x4 super crew. Since your truck is 4wd you are good to tow with all 4 wheels on the ground. You will need to place the transfer case in neutral and engage the four wheel down towing feature. All of the steps be explained in your owners manual and we do suggest reading thru that thoroughly before towing.

  • Flat Towing 2019 Ford F-150 with 5,000 Pound Trailer Hitch on RV
    The 6,500 pound GVW of your 2019 Ford F-150 refers to the most it can weigh with seated passengers and cargo loaded. Since the truck won't have any passengers inside when flat towing it behind an RV it's not going to weigh this much. I looked up the base weight of your F-150 and depending on your exact model and specs it has a weight of around 4,000 to 5,697 pounds. Since the higher end of this range does still exceed the hitch capacity on your RV I highly recommend taking the truck up...

    I have a great solution for you. Since you say that you are looking to flat-tow multiple vehicles, I strongly recommend the Blue Ox Patriot Portable Braking System # BLU37TR. This system is a much more reliable and higher-quality system than a Brake Buddy system. Also, with the Patriot, you do not need any additional extra vehicle wiring to use it in another vehicle. You simply remove the Patriot from the F-250 into the other vehicle. For the F-250, you need the Roadmaster Brake-Lite Relay...
