Features to know about

Clean Front End When You’re Not Towing: Hidden Mounts with Removable Arms

This setup keeps things sleek when you’re not hitched up. The brackets sit tucked back in the grille, nearly invisible once the arms are removed, so you keep a clean front end and don’t have to worry about scuffs or bulky hardware sticking out. When it’s time to tow, the removable drawbars slide into place and disappear again when you’re done.

Quick Hookup Every Time: Twist-Lock, Pin-Release Connection

The drawbars attach and remove quickly with a simple twist-lock design. Each arm clicks securely in place and unlocks with the built-in pull pin—no tools, no fumbling. It’s a fast, solid connection that makes it easier to line things up even if you’re hooking up solo.

Heavy-Duty Build for Long Trips: All-Steel Construction

The computer-cut, all-steel construction is built for strength and consistency. It bolts directly to the frame with no welding required, spreading the towing load evenly across solid mounting points. The black powder coat finish resists corrosion and holds up through thousands of miles of towing, giving you confidence on long hauls.

No Extra Crossbar Needed: Direct-Connect Design for Roadmaster Tow Bars

These direct-connect brackets eliminate the need for a separate quick-disconnect crossbar, so setup is simpler and cleaner. They 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—so everything fits and functions as one streamlined system.

DIY-Friendly Install: Bolt-On Kit with Clear Instructions

Installation is straightforward for anyone comfortable turning wrenches at home. The kit mounts to the frame without welding and comes with all necessary hardware plus clear instructions. Once installed, you get a tight, secure fit that’s custom-built for your setup and easy to maintain over time.

directions very helpful and accurate

They work good

It works just fine



by:

Very Happy I bought this as it didn't require the bumper and more to be removed like some of the other ones.



by:

The parts I ordered are awesome and Etrailer is great to deal with....



by:

Easy install and works great no problems at all



by:

Excellent fit to the existing GMC Silverado AT4 frame. Only made a slight increase in the rubber shrould around the removed tow hooks.
The instructions were for the 2021 year trucks. Mine is a 2022. A few changes had to be made but it looks great when finished.



by:

I can,t tell you anything now until I start installing them.



by:

I take these reviews seriously so others can benefit good or bad from my experience. I cannot express strongly enough how very customer service oriented this company really is. They will make every appropriate attempt to work with you. I dealt with Arthur. He not only found an item I had been told by others including the manufacturer was not available. He also came up with a fall back plan if plan A for some reason did not come through. He had my base plates shipped to my door faster than my installer could believe. Truly professionals! I would highly recommend this company and if you are lucky enough to deal with Arthur you have been blessed with the best customer service person I have dealt with in years! Great Products, Great Inventory, Great Company, Great People.



by:

The base plate was a perfect fit and is very well made. Works great.



by:

Installation was relatively straightforward; my vehicle did not require removal of the bumper, although the instructions indicated that some engine types did. Installing the nut plates (through a hole in the frame), and getting them lined up with the bolts, was difficult to do with a helper, and would be impossible to do with one person. The installed look is excellent, however; when the arms are removed, the baseplate is barely noticeable.



by:

It was a fantastic base plate. The Blue Ox base plates required the entire bumper, grill, etc be removed. These Roadmaster base plates were installed from underneath and only required the tow hooks be removed. My wife and I completed the installation in a couple hours. The stiff wires attached to the nuts that required installing inside the frame was genius. We bought Roadmaster to Blue Ox adapters and continue to use our Blue Ox towing equipment. The Roadmaster Nighthawk is just too heavy for me (I'm 78). Anyway, I love the Roadaster base plates. And, I'm thankful for the clear installation instructions provided etrailer.



by:

went in almost without a hitch .... maybe a redesign of nuts that go through hole with wire attached they are very difficult to get into position! but i did make itlol



by:

Roadmaster makes great baseplates. I had a set on my 2014 Silverado and then I bought a 2024 Sierra AT4. I put these on the AT4. The nice thing about the AT4 with the 6.2 is that the baseplates can be installed without removing the bumper and grill. As such, I was able to DIY it. They have worked well after about 5000 miles of towing.



by:

Fair price, short delivery. All the pieces were there, instructions were good with pictures. Fairly easy installation with no drilling. Rugged construction. I’ve used Roadmaster base plates before and have never been disappointed.



by:

The brackets are heavy and feel solid. The mounting is straightforward on my 2024 GMC Sierra Denali 1500. You will lose the front tow hooks but I feel the tow bracket inserts will be safe to use if needed for a rescue. They are barely noticeable to the casual person when the inserts are removed for daily driving.



by:

I bought and self installed this on my 2021 GMC Sierra Duramax 1 year ago. Install took about 5 hours and wasn't difficult...I could problty install it in 2-3 hours after leaening the tricks. Weve towed the truck all over the USA since then (over 10,0000 miles) and it works great! I've used other brands and highly recommend Roadmaster tow systems over the competition.

Still works great, no issues.



by:

System works as described - installation was difficult. One of the arms holding the nut so you could reach inside frame rail broke before nut was tight, so I had to have another one shipped out and cut off the bolt that was partially installed.



by:

I have a 2019 GMC Denali and this product from Roadmaster is fantastic. Installation was easy with out having to remove the grill or valance or bumper. There was no trimming on the Plastic. The baseplate installed from the rear with a little push and nudge. there was one bolt just a tad long but this was fixed with a washer. If this is your model of vehicle and you don't want to trash the front get this base plate.

Great fit and finish.
Lessons learned,
bend and fit the wire nuts first while you can still see the hole openings, then set aside and follow directions.

  • Is There A Base Plate For A 2024 GMC 1500 AT4X?
    Hey Brian, thanks for reaching out. No, unfortunately we do not have a base plate fit for the 2024 GMC 1500 AT4X. We have several options for the 2024 GMC 1500 but none of them will fit the AT4X model. This is mostly because generally you cannot flat tow a 2024 GMC Sierra 1500 AT4X. Most 2024 Sierra 1500 AT4X trucks do not have a true neutral position in the transfer case that’s designed for flat towing, which is the big requirement for towing four-down.

  • Is Battery Disconnect Required When Flat Towing A 2019 Chevy Suburban?
    Hi Edward, thanks for reaching out. This is a good question, and you’re thinking about it the right way. GM requires the battery to be disconnected when flat towing vehicles like your Suburban because the electronic parking brake can self-activate while the vehicle is in accessory mode. Disconnecting the battery removes that risk entirely, which is why a battery disconnect like the Roadmaster # RM-766 is required. That part is non-negotiable for safe flat towing on these models.

    Hey Chris, thanks for reaching out - those are great questions! You will need a dedicated wiring harness for flat towing your 2025 GMC Sierra 1500, yes. I really like the Flexo-Coil Kit # RM-15267 because of how reliable it is, but if you don't already have a tow bar then I recommend pairing the Nighthawk All-Terrain Tow Bar # RM-676 with the Accessory Kit # RM-9284-2.

  • Why Do I Need to Disconnect the Battery to Flat Tow a 2022 GMC Sierra 1500 AT4?
