Features to know about

Made for a Clean Front End: Hidden Bracket Design with Removable Arms

When you want a base plate that doesn’t change the look of your vehicle, this one fits the bill. The crossbar-style brackets sit far back on the frame so the front end keeps a clean, factory appearance. Once the drawbars are removed, the brackets are virtually invisible within the grille, where they stay tucked away and protected from scrapes and scuffs. You get a neat look with no bulky metalwork in sight when you’re not towing.

Quick Hookup Every Time: Twist-Lock, Pull-Ring Arms

Connecting and disconnecting is simple thanks to the twist-lock design. Just insert each arm into the bracket and twist it until it clicks into place. Built-in pull rings let you unlock and remove them just as easily when you’re done towing. It’s a fast, foolproof setup that makes solo hookups less hassle whether you’re in your driveway or at a campsite.

Strong Where It Counts: Computer-Cut, All-Steel Construction

The base plate bolts directly to your vehicle’s frame so it can handle long-haul towing loads without flex or fatigue. Each bracket is computer-cut from all-steel stock, then finished with a durable black powder coat that resists corrosion and road wear. It’s built for thousands of miles of reliable performance without requiring any welding during installation.

Fits Right and Installs Clean: Custom-Fit Design with Mounting Points

A custom fit means everything lines up where it should for a straightforward bolt-on install—no fabrication or welding needed. Integrated mounting points make it easy to add an electrical connector plug or bracket (sold separately) so your wiring stays tidy and secure. Clear instructions and all necessary hardware come right in the box for a smooth setup from start to finish.

Works with Proven Roadmaster Gear: Compatible with Motorhome-Mounted Tow Bars

This kit works seamlessly with Roadmaster motorhome-mounted tow bars when used with the quick-disconnect crossbar (#910021-00, sold separately). That gives you flexibility to use proven equipment already in your towing setup while keeping everything aligned and easy to manage on the road.

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.

Great product from Roadmaster and etrailer.com. The package was packed wonderfully. Highly recommend etrailer.com for towing needs!

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

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



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.



by:

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:

Work great to tow my Ford F150 behind my motorhome. Very easy to install, great instructions....



by:

I had to take my round chainsaw file to the mounting plates that have nuts welded in place because there was little pieces of metal that had splattered in the threads of the nuts and I couldn’t get the bolts to thread in properly, it took me about 30 minutes to file them down but I was able to do it, so that’s why 3 stars no 5



by:

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.

  • Flat Towing a 2018 Ford F-150 STX Behind an RV
    Your 2018 Ford F-150 STX can be towed behind an RV if it is a Four-Wheel drive model. You'll want to follow the instructions in your vehicle's owner's manual to the letter, as it uses a function of your electric shifting case to switch into a specific towing compatible mode and then back again to a driving mode. If you do have a four-wheel drive model, then you'll need a base plate, tow bar, tow bar wiring, and a supplemental braking system. For the base plate, I recommend Road Master's...

  • 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 2015 Ford F150 Truck Be Flat Towed Behind a Motorhome
    If your 2015 Ford F150 is a 4WD model with a neutral position in the transfer case, you can flat tow the truck by engaging the 4 wheels down towing feature as described in the owner's manual. 2WD vehicles cannot be flat towed. When I looked up the curb weight of the 2015 Ford F150, I saw that the curb weight ranged from about 4000 to 5000 lbs.

  • 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...

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.

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.

To flat tow the F-150 you'll also need base plates, wiring, a supplemental braking system, and likely a high-low adapter.
