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.

This is my 4th set of Roadmaster baseplates that I’ve installed through the years. The fit, quality and finish appearance is always excellent. 2024 Chevy Silverado 1500.



by:

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!

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!!



by:

Excellent base plate, just as my wife requested, she didn’t want too much metal visible in front of the bumper. Installation instructions were a bit confusing for me, but I’ll clarify, for me.



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:

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.
Thanks Lauren A for your help!

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.



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

The Roadmaster Direct-Connect Base Plate Kit has performed flawlessly over the past year. With almost 10k miles logged during our 3 month trip across the US, the components have remained as installed and operated as expected.



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.



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:

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.

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:

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:

Good product, US made.



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.

  • 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...
