Features to know about
Built for Heavy-Duty Towing: Fixed-Bar, Direct-Connect Design
When you’re towing a full-size vehicle, reliability matters most. This base plate kit uses a fixed-bar design with front arms that cannot be removed, giving you solid, always-ready attachment points. The direct-connect setup installs onto the frame and doesn’t require a crossbar, which means fewer parts to deal with and faster hookups every time you hit the road.
Strong Where It Counts: All-Steel Construction with Powder Coat Protection
Each bracket is computer-cut from all steel for exceptional strength and precision fitment. The black powder coat finish resists corrosion and road wear, so it stays looking sharp through years of use. The heavy-duty build spreads towing forces evenly across the frame to keep stress off your vehicle’s front end mile after mile.
Simplified Setup: No Crossbar Needed for a Clean, Efficient Connection
The direct-connect design eliminates the need for a quick-disconnect crossbar, streamlining the whole process. Fewer components mean less time lining things up and more confidence that every connection point is solid. It’s built for those who want a sturdy, no-nonsense setup that’s ready to go when they are.
Straightforward Installation: Bolt-On Fit with Included Hardware
No welding required here—just bolt the brackets directly to the frame using the included mounting hardware. The custom-fit design ensures everything lines up properly for a secure installation. Once in place, it’s a dependable foundation that works seamlessly with Roadmaster tow bars that slide into trailer hitch receivers, including models like the Nighthawk, Sterling, Blackhawk, Blackhawk 2, Falcon, and Falcon 2.

Note
- Important note: Direct-connect base plates will work only with the Roadmaster tow bars that slide into a trailer hitch, such as the Nighthawk, Sterling, Blackhawk, Blackhawk 2, Falcon, and Falcon 2. These base plates will not work with tow bars that require a hitch ball. The EZ Hook safety cables included with Roadmaster's Sterling tow bars will not work with these direct-connect base plates. These cables connect to an anchor plate on the Quick Disconnect crossbar, which will not be present when using these base plates. Direct-connect brackets do not require a crossbar because of the heavy-duty nature of your vehicle's frame.

- Parts Needed to Flat Tow a 2015-2019 Chevy Silverado or GMC Sierra 3500The parts to flat tow a 3rd generation 3500 GM pickup will actually be almost identical whether it is a Chevy Silverado or a GMC Sierra since they are essentially the same vehicle. To flat tow any vehicle you will need a base plate kit, tow bar, safety cables, vehicle tow bar wiring, a supplemental braking system, and possibly a high-low adapter. The base plate kit that I recommend for your application is the Roadmaster MS Base Plate Kit # RM-3180-2 as this fixed arm system adds a rugged...
view full answer... - Will a Baseplate on a 2018 GMC Sierra 2500 Work w/a Grille Guard?Hey Todd, thanks for the information! The Demco Classic Base Plate Kit item # DM9517321 is not going to be compatible with Westin HDX Grille Guards like item # 57-3790. All of the baseplates like item # BLU22QR and item # RM-3180-2 for your 2018 GMC Sierra 2500 install in the same location as well. You'll need to remove the grille guard permanently if you want to flat tow your truck. Here are the parts I recommend for flat towing your 2018 GMC Sierra 2500: Tow Bar and Safety Chains -...

Starting with the base plates, I recommend the Roadmaster MS Base Plate Kit # RM-3180-2. These heavy-duty brackets are confirmed to fit the 2015-2018 Sierra and their all-steel construction provides exceptional strength for pulling the vehicle. All the needed mounting hardware is...
view full answer... - Flat Towing a 2019 silverado 3500 HD DuramaxAccording to the owner's manual, if your truck is a 4x4 model with a 2 speed transfer case that has a Neutral and a 4wd Low setting, it can indeed be flat towed. Two wheel drive models and models with different transfer case settings cannot be flat towed without installing a driveshaft coupling. To flat tow the truck, you'll need base plates, a tow bar with sufficient capacity to tow a truck that could weigh up to 7100 lbs, safety cables, a wiring harness, a supplemental braking system...

Only four-wheel drive vehicles with a two-speed transfer case that has a Neutral and a 4-low setting can be towed four wheels down. The negative battery cable must be disconnected and not touch the terminals. Also use of a shield mounted in front of vehicle grille could restrict airflow and cause damage to the transmission.

view full answer... - Parts Needed to Flat Tow 2015 GMC Sierra 2500Yes, your 2015 GMC Sierra 2500 can be flat towed, and you MUST have a light kit and a supplemental braking system is also required by law in most states so you can check with your local authorities to find out if it is required where you are going to be flat towing. There are a number of parts you're going to need in order to do this, starting with compatible base plates. I recommend the Roadmaster MS Base Plate Kit # RM-3180-2 so long as the truck is a 4 wheel drive, which I assume it...
view full answer... - Parts Needed to Flat Tow a 2018 GMC Sierra 1500 Behind a MotorhomeWe do have base plates for your 2018 GMC Sierra 1500 but # RM-3180-2 will not fit. The comparable set that will fit your 1500 is # RM-3177-3. This set actually has removable arms so that when you take them out the base plates are essentially invisible. I have linked the installation instructions for you to view. For a compatible tow bar I recommend the Blackhawk 2 # RM-422. This is an all-terrain tow bar which means you will not have to be lined up perfectly straight and level to hook...

These are custom fit for your truck. For a compatible tow bar I suggest the Roadmaster BlackHawk 2 All-Terrain # RM-422. The BlackHawk 2 AT fits into the 2 inch receiver at the back of your RV. It connects to the MS Base Plates using included pins and clips. I've attached a video for you to check out. You'll also need safety cables, like # RM-653. For lighting you can use the...

For a 10k rated tow bar you would want the Roadmaster Blackhawk # RM-422. For safety cables you would want the part # BX88197. Since you already have supplemental braking all you need is tow bar lighting. For that you would want the # RM-155 which wouldn't require you to mess with splicing any taillight wiring.
