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.

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!!

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:

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:

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!



by:

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

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:

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:

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.



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:

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.
