Features to know about

Built for a Factory Look: Hidden Direct-Connect Design

If you want your front end to stay clean when you’re not towing, this setup handles it neatly. The direct-connect brackets mount to the frame but sit farther back than standard styles, so they’re virtually invisible once the drawbars are out. There’s no bulky quick-disconnect crossbar, and the remaining brackets tuck behind the grille where they stay protected from scrapes and scuffs. It keeps everything looking stock while staying ready to tow at a moment’s notice.

Quick Hookup Every Time: Twist-Lock, Removable Arms

The removable drawbars slide into the brackets, twist to lock, and click securely in place. When it’s time to disconnect, just pull the built-in ring to release and twist them out—no tools, no hassle. This makes hookups faster whether you’re in the driveway or out on the road. The self-locking design gives a solid connection that feels dependable mile after mile.

Strong Where It Counts: All-Steel, Computer-Cut Construction

This base plate’s computer-cut, all-steel build gives it exceptional strength while keeping tolerances tight for a perfect fit on the frame. The black powder coat finish holds up against corrosion and road grime over time. It bolts on with included hardware and requires no welding, so once mounted it becomes a sturdy, integrated part of your towing setup.

Made for Long Hauls: Compatible with Motor-Home-Mounted Tow Bars

The system is designed specifically for Roadmaster motor-home-mounted tow bars that slide directly into a trailer hitch—like the Nighthawk, Sterling, Blackhawk, Blackhawk 2, Falcon, or Falcon 2 models. That direct connection eliminates extra pieces between your RV and towed vehicle for a solid, reliable link built to handle serious miles on long trips.

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



by:

I watched YouTube videos on how to install. I have used this a year now. It is well made and not some cheap junk. Heavy steel and I am pleased with it. As with all etrailer products I have purchased, I highly recommend. Their customer service is outstanding.



by:

Bolted right up to my 2021 Ford Expedition Max Platinum. No issues and is a snap to hook up and unhook the tow bars. The units poke right out the factory openings and are hardly noticeable when the draw bars are removed. About the only complaint I have is that the draw bars fit sloppy in the base plate adapters. They wobble a LOT but are made of very thick steel. After about 3000 miles towing so far, the draw bars are pretty heavily worn where they contact the base plate adapters.



by:

Quality product for my new 2024 Ford Escape Hybrid AWD ST Line. Came with decent instructions that got me through installation without issue. Installation required drilling only two holes through the plastic lower grille opening for the insertion of the tow arms. Everything else was completely "bolt-on". The breakaway switch, safety cable tabs, and the wiring receptacle all fit through existing openings in the lower grille providing a "clean" finished look.



by:

I originally purchased a Blue Ox baseplate to install since I already had a tow bar. Upon removing the front grill, I was surprised to find the used Element I had purchased already had the front bumper caps removed and 2 braces installed. Thanks to the photos on etrailer reviews and product info, I was able to determine that the vehicle had previously had a roadmaster baseplate installed! I purchased this unit and it fit perfectly onto the already installed braces. Seems very solid and high-quality so far.

A clean look on my 2025 Ford Maverick Hybrid after following e-trailer's detailed installation instructions.



by:

Installation was fairly straightforward, kudos to e-trailer for the videos, looks great, everyone says it looks factory installed, love the low profile base plate without the bar, also love that the hook ups are detachable and can be removed when not towing, gives it an overall cleaner look. Installed it right at the campground without issues, took about 3 hours to install, with our rubicon only had to widen the top holes as the second set of holes were already the size of the bolts needed. This is the 3rd base blare we have installed and they get easier each time.



by:

Put this on a 2014 Honda CR-V. This is a very well made base plate setup! The overall design, welds and powder coating are outstanding! Shipping was super fast too! The install video by etrailer was close to perfect and really helped to take the "scary" out of doing the job. The only change I would like to see in the video is during the grill removal. He says to just yank it forward to get the clips to release. Unfortunately, most of the specialized clips broke doing it this way. Had I known, I would have slipped a thin tool just below the grill to get the clips to unlock/release. Also, on the wrap around, bumper cover, some of the tabs on the bumper cover ripped out and I had to do some creative plastic welding or fiberglass resin/cloth to repair. These clips have a release tab also. I suggest finding specific videos on youtube to remove the plastic body parts and grill. I got it all done and it works perfectly! I really love the almost invisible tow receivers on the car (when the arms are removed). Our last toad was a 1997 Nissan Hardbody pickup that has permanent knee busting/shin smashing protrusions. I am super happy with everything we have bought from etrailer over the past 18 years!



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!



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:

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.



by:

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:

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



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:

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:

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:

It works pretty good.



by:

We have the base plate and hitch installed and all is good. Thank you for the great service. It was received promptly. We have always had great service and appreciate the knowledge of the people who represent you. Ty Mollie.

    A supplemental braking system is a requirement in most states now, so you would need to consult your local state laws to find out if it is required where you live.
