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.

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:

Good product. If you are reasonably handy and have some tools, you can install this yourself in a few hours. I'm a mechanic, it took me a little over 2 hours to install on my own toad. The fit is good, there are 4 holes you have to drill, otherwise it is plug and play. When you insert and twist lock the tow bar mounts into their sockets they feel a little sloppy but they are secure, and i never noticed any rattle when towing. Overall i give it a 4 out of 5 for easy install and clean look after install. Pic included of installed base plate.

This was a bit of a challenge to install on a 2026 Chevrolet Colorado Z71. One item to be aware of, as you take off the front Facia of the truck for the install, there are two Facia "brakets" that attach to the front fenders that seem like they are use once plastic snaps. Three of the 4 snaps broke off on both sides when I removed the facia. These are about $35 a piece from Chevy and prevent you from making this a 1 day job. Additionally, there are 2 7mm screws/bolts that connect one of the coolers to the back of the bumper support and these are a real problem to get back in - over an hour of time and every 1/4" tool in my arsenal was needed to find a way to get these started. Finally, one of the Connecting Plates (Passenger side) needed to holes to be elongated to enable all the bolts to be started. Finally - you need to put the Brakaway bracket on the driver side, to have enough cable to reach you brake system. Probably have 4 hours in the disassembly and installation of the Direct-Connect Plate. Now waiting a couple days for the plastic brackets from Chevy to complete the install. Good Luck!!

The folks at etrailer are fantastic. I didn't know everything I needed to tow my car behind our RV... but they did! Everything I needed was in the boxes and the videos made it all come together. Thank you to everyone at etrailer!



by:

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



by:

Very fast shipping, and the install was easy. Great product



by:

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



by:

Easy installation! Etrailer videos are very informative and helpful! Always great to have a helper too!



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:

It was shipped promply. I installed it myself using the included step by step instructions and videos from etrailer. It all went well (though I had to come back and reconnect the sensor plug- my bad).
I tow a Jeep Grand Cherokee Trailhawk and this base plate is nearly invisible when not towing. Works 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.



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:

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.



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.

The whole process of working with etrailer was excellent. Jamie was very helpful and knowledgeable.



by:

Very heavy duty. Have not installed yet, hopefully they fit



by:

Had to cut way to much of the bumper cover. Could easily be designed to fit with much less cut out.



by:

Good product, US made.



by:

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.



by:

The instructions in the box were for a GMC not a Chevrolet. Fortunately you have a YouTube video specifically for my truck and it was great. Instalall was successful.
Thank you so much for the chat option on your website, I almost ordered the wrong kit.

  • Parts Needed to Flat Tow 2022 GMC Canyon AT4 With Roadmaster Falcon 5250

  • 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.
