Features to know about

Built for a Clean Front End: Streamlined Direct-Connect Design

If you like your setup to look clean when you’re not towing, this base plate keeps things tidy. The hidden design eliminates the need for a quick-disconnect crossbar, and the direct-connect brackets sit even farther back than standard mounts. Once the removable drawbars are out, the brackets stay tucked up and out of sight for a factory-style look.

Hook Up and Go: Twist-Lock Removable Arms

When it’s time to tow, the arms click right into place—no tools, no hassle. Just insert, twist to lock, and you’re set. Built-in pull rings make it easy to release and remove each arm when you’re done. The twist-lock attachment keeps the connection secure while still being quick to handle solo.

Solid When It Counts: All-Steel Construction with Powder Coat Finish

This kit bolts directly to the frame with no welding required. The computer-cut, all-steel construction provides exceptional strength, and the black powder coat finish helps resist corrosion through years of use. It’s built to handle real miles and long hauls with confidence.

Simple Setup in Your Own Garage: Custom Fit with Included Hardware

Everything comes ready to bolt on using the supplied hardware and instructions. Each base plate is custom built for a perfect fit on your vehicle’s frame, so alignment is straightforward and no welding is needed. It’s a solid weekend project that leaves you ready to roll.

Keep Your System Consistent: Works with Roadmaster Motor-Home-Mounted Tow Bars

This direct-connect base plate works exclusively with Roadmaster motor-home-mounted tow bars that slide into a trailer hitch—models like the Nighthawk, Sterling, Blackhawk, Blackhawk 2, Falcon, or Falcon 2. Once installed, it gives you an easy, reliable way to connect your existing Roadmaster setup without any extra crossbar hardware.

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.

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!!!

9/23/2026

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

Larry

9/23/2026

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.

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.

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: TC 10/10/2026

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.

I had hoped to employ a mounting bracket assembly I had bought on-line used. It would have required extensive modification with an unsure outcome. I found this assembly at etrailer for a reasonable price and ordered it to remove uncertainty from the installation. Etrailer was helpful in completing the rest of my needs for a brake assembly also. Good people.

I really like the way it is hidden and doesn't stick out like a sore thumb. My Rubicon X has a metal skid under the bumper that I cut holes in for the base plate tabs to protrude. I made 5 or 6 trips to my shop to get it right. Would be nice if it came with a paper template showing where to trim. It bolted up perfectly and seems well made.

2018 Mazda Miata

I installed this base plate on a 2018 Miata RF. I think I recall something about it taking 3.5 hours and my initial estimate was 3.5 days. It actually took a bit longer than that, but I was not pushing myself and did not have the luxury of having the vehicle on a lift but had it up on two ramps for the front wheels.

The order came pretty quickly, probably about 4 or 5 days between the time I placed it and UPS delivered it. The parts were well packaged and it came with a printed set of instructions. I had watched the video install on another Miata and if it weren't for that I'm not sure I would have tried it. I'm not a pro mechanic by any means but have worked on my own vehicles now for over 40 years. And I'm not a spring chicken either, so all the up and down working on the car can tire me fairly quickly. But if you are not in a rush and go carefully it can be done.

It took a day to do most of the disassembly. I removed both headlights and the intake tube on the passenger side. That tube came out much easier then it went back in.

The next day I got the baseplate mounted which helped to start visualizing how it all would work. All of the holes for the 6mm bolts did not quite line up with the holes in the frame. I had to file one sides worth for a bit of extra clearance. From my experience on this install you really want to leave all the bolt on the loose side till you get everything situated.

A couple of days off for rain and the then I got to work on the bracing. Initially I though I didnt need to cut the top lip of the frame but I decided to go ahead and do it anyway since that part didnt seem to sit flat when bolted from the back end. I'm still not sure its really necessary as the hump clears the metal lip without cutting it.

I also ordered a 14" long 1/2" drill bit to cut the holes in the frame. It was a Bosch bit, wasnt very expensive and it went through the metal like the proverbial hot knife. I managed to get all the big bolts installed in a day with a great sense of satisfaction.

The next day I torqued down all the bolts and the mount felt very solid. They stress that you need to install all the bolts, but honestly I can't see the 6mm bolts doing much compared to the half inch bolts that do most or all of the work. But I put them in and tightened them all the same.

A couple of days spent to install the tail light wiring and then I got back on to putting the front clip back on. My car must have had an aftermarket grill since it did not match the pictures or the video. I tried to position it carefully to see where the parts that were going to stick out would be so I didnt cut out more than I needed to. So there was a good amount of back and forth, cut and fit. In the end I had to make some extra cuts for clearance for the safety cable tabs as well as the mount for the 6 wire connector. Until I made the extra cuts the lower part of the front clip would not seat correctly. Getting the clip in the right position so it fits under the lights also takes some finagling.

Figuring out where all the bolts go back in can be interesting. Take pictures where you can. Dont be too aggressive when working with plastic parts. Overall I'm satisfied with the install, but I have yet to try and hook it up to tow.

2002 Honda CR-V. Easy to install. Two and a half hours, and stopped to eat a sandwich. To install the spacers inside the roll frame on the car I used an extension magnet to reach in there and position them. As you can see NO cutting was needed on the bumper cover!
Now I have to figure out the easiest way to run the wiring for the lights.

Install for the base plate looks awesome, Joe! Unsure if you have a wiring kit yet but there are a few options so I'll go ahead share them with you here in case you don't yet. The most popular kit would be part # RM-15267. This can be difficult to install but it is the most reliable. I've also linked an install video for this kit. Something that still has an integrated look but easier to install I would go with part # RM-155. You do have to drill some holes into the back of the light housing, so if you're okay with doing that, this may be the better kit. Also included an install video for that kit as well. Hopefully the videos will help you get a good idea of how to run the wiring for your lights. Let me know if you have any questions after watching!

Parts Needed to Flat Tow 2022 Chevy Colorado ZR2 Behind Motorhome
We'd be happy to help with that. As long as your Colorado has a transfer case that has a Neutral and a 4 wheel low position, it can indeed be flat towed. For base plates, I'd recommend the Roadmaster Direct Connect base plate kit, part # RM78VR which Roadmaster confirms is compatible with the ZR2 package. For a tow bar, I'd recommend the Roadmaster Falcon All-Terrain tow bar, part # RM-522. You'll also need # RM-643 safety cables. To wire the taillights, use the # RM-152-98146-7 diode...
