Features to know about

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

When you’re not towing, you still want your front end to look clean. The streamlined design of this kit sits even farther back than standard brackets, leaving almost nothing visible once the drawbars are removed. The hidden brackets mount within the grille area, where they stay out of sight and protected from scrapes. It keeps the factory look intact without the bulky quick-disconnect crossbar up front.

Hook Up Fast and Get Rolling: Twist-Lock, Quick-Release Arms

Connecting your tow bar shouldn’t take all afternoon. The removable arms on this setup click to lock in place and twist out when you’re done. Built-in pull rings let you release them easily so you can remove and stow the arms in seconds. The direct-connect design mounts right to your motor-home-mounted tow bar, making it the simplest Roadmaster system to connect and disconnect.

Strong Where It Counts: All-Steel Construction with Powder Coat Finish

Durability matters when you’re logging miles behind a motorhome. This base plate uses computer-cut, all-steel construction for exceptional strength and a black powder coat finish that resists corrosion. The brackets bolt directly to the frame for a solid connection point without the need for welding. It’s a heavy-duty setup built for long stretches of road.

Simple to Install and Fit Right: Custom Plates with Included Hardware

No fabrication or welding is needed here—each kit is made with custom base plates that ensure a perfect fit for your vehicle. Everything bolts up using the included instructions and mounting hardware, so it’s straightforward for a DIY install or a quick job at the shop. Once it’s in place, the connection points line up ready for your Roadmaster motor-home-mounted tow bar such as the Nighthawk, Sterling, Blackhawk, Blackhawk 2, Falcon, or Falcon 2 models.

Thank you so much for the chat option on your website, I almost ordered the wrong kit.

Sturdy, simple to use design. The second set if Roadmaster base plate lits I have installed. (2015 Silverado and 2022 Colorado). Both work well. And oh yeah, do yourself a favor and buy from etrailer. If you have any hitches in the get along, those good folks will always help straighten things out.

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.

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.

I’ve pulled the Chevy behind our motor home several times over a the last year. It has worked excellent. And when not in tow the tubing is barely noticeable.

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.

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!!!

Which trim is your 2026 Chevy Trax? Per Roadmaster, the # RM25EQ (523228-5) fits all trims of the 2026 Trax except the ACTIV trim....

The 523228-5 DOES NOT FIT MY 2026 CHEVY TRAX LT! Look at the side braces in your video of a Demco base plate install (upside down "U"). That is what is needed for my install. In Roadmasters install instructions, page 7, items #2, #3 have no frame in that area to bolt to & #5 has only one ho l e on bact end and putting a bolt in that hole leaves 3/4" short of main base plate. I sent pics to verify this to Noah on 9/22 @ 11:46AM. I know, unless you tried this install personally you are going by Roadmaster's word. BE CAREFUL IN SUGGESTING THIS FIT UNTIL YOU VERIFY. I just do not want someone else to have this experience. Thoughts ?

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.

It’s been a great year. No problems with the base plate. Works great with my tow bar. Towed my trailblazer from Texas to North Dakota and back, and several short trips.

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

2013 jeep Wrangler
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.

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:
It’s a super strong and wonderfully engineered addition to my new Maverick pickup.. Couldn’t be happier with it!!!!! Well done!!!!
by:
The product is great - I gave 4 vs 5 stars only because I had to drill the rear holes out as they did not align with the holes in my frame and I had to drill out the hole in the bracket to align with my frame extension hole, again bracket did not align with the existing hole. However, in general it appears to be a solid mount.
by:
Great Base plate, had to modify the non-oem bumper a little to get the clearance needed to get mounting holes lined up. Once that was done, everything went pretty quickly finished and tested. Towed 600 miles and worked flawlessly. Much better than using the bumper tow points, as they were elevated causing a very bouncy towed on bridge aprons. Bumper tow points also let the towed have minor side to side movement, this does not, so a lot better towing experience.

  • Parts Needed to Flat Tow 2022 GMC Canyon AT4 With Roadmaster Falcon 5250
    Hey Gerald! I would be happy to help you out with this. The correct base plate kit for the AT4 is the Roadmaster Direct-Connect Base Plate Kit # RM27MR. This will be compatible with your Falcon 5250. If you don't already have safety cables you will also want the # RM-643. The Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles # RM-15267 is the best wiring option for your truck. You will also need the Roadmaster Battery Disconnect # RM-766 or if you have a diesel the # RM93MR. If...

  • Can I Flat Tow My 2021 Chevy Colorado 4x4 Z71 V6 Engine
    Hi Melissa, great question and I’m really glad you checked before setting this up, because this is one of those situations where getting it right matters for protecting your drivetrain. For your 2021 Chevy Colorado 4x4 Z71 with the V6, the short answer is yes, you can flat tow it, but only if it has the proper transfer case. Your truck needs to be equipped with a two speed transfer case that has a true Neutral position. That Neutral setting is what disconnects the drivetrain so nothing...

  • What's The Difference Between The Roadmaster Baseplate Kit # RM27MR And # RM37VR
    The difference between the Roadmaster Baseplate Kit # RM37VR and # RM27MR is that the # RM37VR will not fit AT4 models and the # RM27MR is designed to fit AT4 models. You'll just need to choose the corresponding option for your specific model.
