Roadmaster Tow Bar Base Plate - RM-524431-4

  • 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

The drawbars, or front arms, on the crossbar-style series 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, simply twist the arms back and pull them out. 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.

Watched the videos of the install.. Uber easy. Was able to do by myself in about an hour and fifteen minutes. I recommend running the bolts through all the tab nuts before trying to assemble (clean the paint out of threads) Otherwise easy peasy. Spoke to customer service pre-sale to make sure I had everything. Rep was very understanding and found the listings for the parts I needed and put them all in a cart for me. Will continue to shop etrailer FIRST as install videos and customer support are in a league of their own and miles above everyone else.

I purchased the Roadmaster Crossbar-Style Base Plate Kit w/ Removable Arms, The Roadmaster Nighthawk Tow Bar, Quick Disconnect Crossbar, Universal Hy-Power Diode Wiring Kit, and Roadmaster Guardian Rock Guard in order to tow my 2020 Ford Raptor behind my Class A. Everything bolted on beautifully and the craftsmanship was fantastic. Ordering from etrailer was easy and the parts arrived within a few days with no problem. I watched numerous [online] videos to learn how to install everything and they saved me a lot of time. Overall, I'm very happy.



by:

Typical excellent Roadmaster quality. I installed these myself in something less than two hours. These are very heavy duty and give me confidence that my 2016 F150 will stay attached to my motorhome using the Roadmaster Sterling towbar.
I am very happy with the purchase and the service I get from etrailer.

Base plate was an exact fit for my vehicle and has Worked as expected.

Product has held up well and works as advertized



by:

This was the easiest baseplate I have ever installed, and this was the third vehicle I have put one on. Only one hole has to be drilled in each frame member and the rest are bolts. This works great and it hides away well so that nothing is sticking out when you’re not using it.



by:
2018 Ford F-150

I installed all the products that were purchased from etrailer.com with the assistance of the videos. It was helpful and it saved me from having to pay someone to do the work for me.

etrailer.com is a great website to purchase all one's needs for towing equipment.

Thank You

Product arrived in good condition with all necessary components, well made and fit good. The directions were fairly good, but did have some vague spots requiring me to find a [installation] video for clarification thusly the 4 star rating.

  • Roadmaster Base Plate Kit that Fits 2018 Ford F-150 with Roadmaster Falcon Tow Bar
    Yes the Roadmaster base plate kit part # RM-524431-4 is a fit for your 2018 Ford F-150 and would work great with the Roadmaster Falcon tow bar part # RM-520.

  • Can The Arms From The Roadmaster Direct-Connect Base Plate Kit Be Used On The Crossbar Style Kit?
    You would not be able to swap the arms from the Roadmaster Direct-Connect Base Plate Kit # RM-524431-5 with your Roadmaster Crossbar-Style Base Plate Kit # RM-524431-4 as the arms for these base plates are made specifically for those base plates. However, If you have the Blackhawk 2 All Terrain # RM-422, Falcon 2 # RM-520, Falcon All Terrain # RM-522, Nighthawk All Terrain # RM-676, Sterling All Terrain # RM-576 tow bars, then you can just use the adapter # 910021-00 to be able to use...

  • Roadmaster Crossbar-Style Base Plate Compatibility With A Roadmaster StowMaster 5000 Tow Bar
    The Roadmaster Crossbar-Style Base Plate Kit # RM-524431-4 is compatible with a Roadmaster StowMaster 5000 tow bar and is compatible with your 2016 Ford F-150, however you will need a higher rated weight capacity tow bar to tow an F-150 than the StowMaster 5000. I recommend the Roadmaster Falcon 2 Tow Bar # RM-520. The large hookup radius makes connecting a breeze at any angle, even if your vehicle isn't perfectly lined up with your RV. It has a self-aligning design, you'll just hook up...

    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. For your wiring, the Roadmaster Universal Hy-Power Diode Wiring Kit # RM-154 you asked about will work as it is a confirmed fit. If you have more questions about your flat tow setup or...

For your braking system the SMI Air Force One Supplemental Braking System for Motor Homes with Air Brakes - Proportional # SM99243 is an excellent option.

  • 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...

    To flat tow any vehicle, you will need a base plate kit, tow bar, safety cables, tow bar wiring, and a supplemental braking system. I suggest the Roadmaster EZ4 Base Plate Kit, # RM-524431-4 for your 2019 F-150. These are confirmed to fit this truck and feature a hidden bracket design that will give your truck a nice, clean look. I highly recommend the Roadmaster Falcon All Terrain, # RM-522 as this tow bar has a weight capacity of 6,000 pounds and a non-binding design that will allow...

  • 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...

    For your 2020 Ford F-150, you're going to need a set of tow bars, a braking system, wiring, and a base plate kit. For a base plate kit, I recommend going with the Roadmaster Crossbar-Style Base Plate Kit # RM-524431-4. This base plate creates a slick, hidden design when not installed, and feature a simple installation with no welding required.

  • 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...

    In order to tow your 2012 Ford F-150 behind your RV, you will need a base plate kit, tow bar, safety cables, tow bar wiring/lighting solution, and a supplemental braking system. Starting with the base plates, if your F-150 Platinum has the EcoBoost or 6.2L engine, I recommend the Roadmaster EZ4 Base Plate Kit # RM-524431-4. If your F-150 Platinum does not have the EcoBoost, then I recommend the Roadmaster XL Base Plate Kit # 495-1A. Both of these base plates feature a nice, hidden bracket...

For instance, if your 2014 Ford F-150 4x4 has baseplates # RM-524431-4 or # 495-1A then you will need that crossbar but if you have baseplates # 495-3A or # RM-524431-5 then you will not use it.

This comes with a round 6-way connector that you will install on the front of your towed vehicle and enough coiled wire to go from there to the RV.
