Features to know about

Built for a Clean, Factory Look: Hidden Direct-Connect Brackets

This setup keeps the front end looking sharp. The streamlined design eliminates any obtrusive quick-disconnect crossbar, and the brackets sit far back so nothing bulky sticks out when the drawbars are removed. With the arms off, the remaining mounts are tucked inside the grille, protected from scrapes and giving the vehicle a clean, factory appearance.

Quick Connects That Make Hookup Simple: Twist-Lock Removable Arms

Hooking up takes just a few seconds. Each drawbar slides into the bracket, twists to lock in place, and clicks securely. When you’re ready to disconnect, pull the built-in ring to release and twist the arm free. The system is smooth and intuitive—ideal when you’re setting up solo or making a quick departure from camp.

Strength You Can Count On: Computer-Cut, All-Steel Construction

This base plate kit bolts right to the vehicle’s frame with no welding required. Its computer-cut, all-steel build provides exceptional strength and rigidity for dependable towing mile after mile. The black powder coat finish fights corrosion from weather and road grime, helping it stay solid through long-distance trips and cross-country hauls.

Made for Reliable Pairing: Roadmaster Motor-Home-Mounted Tow Bars

Designed to work exclusively with Roadmaster motor-home-mounted tow bars that slide into a trailer hitch—like the Nighthawk, Sterling, Blackhawk, Blackhawk 2, Falcon, or Falcon 2—this setup removes the need for extra adapters or a hitch ball connection. The result is a cleaner, more direct link between your motorhome and towed vehicle for consistent performance on the road.

DIY Ready with What You Need: Bolt-On Fit and Included Hardware

Everything required for installation comes in the box—mounting hardware plus clear instructions. There’s no welding involved, and the custom design ensures a precise fit on the vehicle’s frame. It’s a straightforward bolt-on project that confident DIYers can handle over a weekend before heading out for their next towing adventure.

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.

I will have our customer service team reach out to you. I reached out to the manufacturers and did find that if the 2018 GMC Acadia has active shutters then the base plate will not be a fit. I do not have one to offer that would be a fit.

Called and spoke to a representative and got everything I needed to set up my GMC Acadia for dingy towing. Great knowledgeable staff. I always can count on them.

Very happy with this Roadmaster baseplate for my GMC Acadia! It is almost invisible when the arms are not installed. And I'm really glad I got the system that eliminates the crossbar - one less step in the hooking up process!



by:

This thing made me nervous.. I was reluctant to remove the facia off a brand new car. The instructions were usable and made removal a breeze, I was actually surprised hiw easy it was. Of note: when you remove the upper screw in the wheel well and the screw inside that holds the fascia to the fender, the plastic piece withbthe screw holes will fall out, I initially thought I broke something but thats not the case.
Installation of the tow bar was really easy even by your self. The exploded view of the instructions were more helpful than the written instructions. Took about 2 hours total. Installing the facia was really easy. I did find it was easier to cut the facia with a jig saw once it was installed. You can hang Tha facia on the 2 screws and let it hang. Cut the holes and push it in the last 2 inches.

No issues after 10K miles, paired with the falcon 2 tow bar its a very solid connection.

  • Does a 2019 GMC Acadia Need to be Placed Into Neutral for Flat Towing
    Good to hear from you again, Harley! You will need to place your 2019 GMC Acadia into neutral when towing, but according to page 361 of your owner's manual it looks like you'll need to lift up the boot around the shifter and press the "manual release button" to do this. I highly recommend referring to the instructions in your copy of the owner's manual to make sure you get your vehicle set up correctly. For a complete flat towing setup you will need a base plate kit, tow bar, safety...

    I looked up the owners manual for you 2019 GMC Acadia and it says that both FWD and AWD models with the 3.6L V6 can be towed with all 4 wheels on the ground. If you have the 2.4L L4 it states that it is not designed to be towed with all 4 wheels on the ground. I recommend that you verify what the owners manual states and verify how your Acadia is equipped. The manual will also outline the procedure of how to put your Acadia into tow mode before your trip.

  • Can the 2019 VW Jetta Be Flat Towed?
    Unfortunately, it's not quite that simple because not all FWD vehicles have transmissions that can be disengaged that will allow for flat towing. You'll want to consult your owner's manual for confirmation but from what I've found it looks like the 2019 VW Jetta, which is FWD, can only be towed on a tow dolly like the Demco Kar Kaddy # DM9713045 . For vehicles that are able to be flat towed, you need a number of components in order to flat tow including base plates, a compatible tow bar,...

  • Can 2018 GMC Acadia Denali with Adaptive Cruise Control be Flat Towed
    I did some checking on the flat towability (I think that's a word) on your 2018 GMC Acadia and found that as long as yours has the V6 engine size it's flat towable as long as you follow the guidelines in the owners manual. There was no exceptions to this based on adaptive cruise control. The four cylinder models would need to be towed on a tow dolly like the # RM-2050-1. So for a base plate kit you'd want the part # RM-523189-5 which is the easiest to connect and disconnect from. I attached...
