Features to know about

Made for a Clean Front End: Hidden Brackets with Removable Arms

This setup keeps the front of your vehicle looking stock when you’re not towing. The direct-connect brackets mount back within the grille, so when the drawbars are removed, there’s nothing bulky left sticking out. The streamlined design eliminates the need for an obtrusive quick-disconnect crossbar, giving the front end a clean look while keeping the brackets protected from scrapes and scuffs.

Hook Up Fast and Confidently: Twist-Lock, Pin-Release Connection

The drawbars slide into place and twist to lock securely in the brackets—no tools or extra steps needed. Each arm has a built-in pull ring that releases the lock so you can twist and remove it in seconds. It’s a straightforward design that makes connecting or disconnecting simple whether you’re at home or on the road.

Built to Handle the Long Haul: All-Steel, Computer-Cut Construction

This kit bolts directly to your vehicle’s frame and spreads towing forces evenly for a strong, stable connection. The computer-cut, all-steel construction gives it exceptional strength, while the black powder coat finish adds durability and corrosion resistance through years of travel. There’s no welding required, and all the mounting hardware is included.

Seamless Fit with Proven Gear: Direct-Connect Design for Roadmaster Tow Bars

The base plate is built specifically for motor-home-mounted Roadmaster tow bars that slide directly into a trailer hitch—such as the Nighthawk, Sterling, Blackhawk, Blackhawk 2, Falcon, or Falcon 2. This direct-connect setup removes extra parts from your towing system and keeps everything aligned for a solid fit every time.

Note

  • 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.

It’s a super strong and wonderfully engineered addition to my new Maverick pickup.. Couldn’t be happier with it!!!!! Well done!!!!



by:

I have lots of issues with this tow bar. Initial installation was difficult due to a tight fit. Had to have my mechanic cut holes in frame to get bolts attached. After a few times of use the bolts failed causing the bar to fall fwd that then damaged my hitch arms. To fix I drilled new hole through bar and frame securing it with a #8 bolt. To reinforce it I used turnbuckles attached to my bumper. last tow finally went well.



by:

I bought and installed this tow plate one year ago on my 2013 Jeep Wrangler. I bought this particular plate due to the jeep having a Barricade off-road bumper. This plate attaches a bit lower than other plates and prevented having to modify the bumper. Installation was easy involving only hand tools. The plate comes with all needed bolts and attachments. I have towed this Jeep several thousand miles behind my RV with absolutely no issues. As an aside, I use a Roadmaster Night Hawk tow bar which is also an excellent product. Both are expensive, but I believe cheaping-out on safety is no a good idea. I highly recommend this product.

Customer service was very helpful.
Easy to install. No bumper or grill cutting however, you do loose your front hooks. Nice low profile.



by:

This works perfect with my Roadmaster tow bar. It was a little difficult to install since I had to remove the front end of the Trailblazer, but with the good directions that came with it and some you tube videos made the installation easier.



by:

Pathetic and just talking to Noah he states he will get to my issue later when he has time!! My car is on jacks all torn apart and I think Roadmaster gas misled advertising. This 523228-5 baseplate is NOT MADE FOR 2026 CHEVY TRAX!!!



by:

It mounted up just as the instructions said it would. From previous research I was not surprised when some of the mounting did not align perfectly. Had to use a dremel tool to make it work. The product looks very sturdy from its design. I’m happy with it and look forward to RV traveling.



by:

Awesome instructions! Install was fairly easy. Product is very high quality and solid construction. Thank you E Trailer!



by:

Easy to install needed to replace some fasteners as they broke removing front grill was able to get them from Amazon cheap



by:

This Road Master Direct connect base plate works perfectly for a 2020 ford transit cargo 250! Awesome service from etrailer as usual! The finished product can barely be seen through the front fascia!



by:

Etrailer comes through again! This was a great savings as a used kit, but it was even better than the description online. I have installed (4) baseplates on and etrailer.com has given me great videos to watch and good instructions to follow. Couldn't be more pleased with the quality, service and delivery times.



by:

Had these installed at Lester’s Automotive in Boerne,Texas…First class service all the way. Paul and his crew worked through lunch for over 4 hours to install these on our 2026 Ford Ranger. Also ran the wire and hooked up my auxiliary tow lights. The price for this was very reasonable and would highly recommend them for all r.v. needs even if not real close to the Boerne area. R.V park within reasonable distance if needed.

Got vehicle apart and found out the item that I am installing does not allow for the reinstall of my tow hooks.



by:

I have enjoyed every product.I have got from etrailer.It's always been top-notch and their service is excellent.Thank you guys so much



by:

Functional, but wish I had ordered Blue ox instead.
Did not fit like the pictures and required cutting the bumper and removing the pretty chrome hooks. Not as clean a design as others I have used. Very unsightly compared to the competition.
