etrailer SD Tow Bar dimensions

Note: If you use this tow bar in the rise or drop position you may need to add safety cable extensions (sold separately) to reach your tow vehicle's hitch.


Works with Roadmaster Direct-Connect Base Plates

Compatible with Roadmaster Direct Connect baseplates with these Adapters

If you already have a Roadmaster Direct-Connect base plate or are planning on getting one, this kit includes the needed brackets to make this tow bar compatible. Simply unbolt the existing brackets and bolt on the new ones in their place. All the hardware is included.


Easy Hookup: Self-Supporting Arms

The etrailer SD has a lot of smart features that give you the flexibility to hook up your toad (towed vehicle) to your RV, without the need for your vehicle to be perfectly level or in the exact right spot.


etrailer SD Tow Bar Self-Supporting Arms for Easy Hookup

First of all, the arms are self-supporting, meaning that they hold themselves up without your help and won't fall to the ground when you let them go. They also move independently of each other, so you can focus on getting just one arm connected at a time. You'll never be stuck wrestling with a heavy tow bar.


Just slide the tow bar into your hitch and pin it in place. The telescoping arms will extend, pivot, and tilt to the needed length and angle to reach the tabs on your base plate. You can get hooked up and on with your adventure.


Once the tow bar's connected, slowly pull forward and the self-aligning arms will fully extend and lock into the towing position. Double check that the arms are properly latched and you'll be ready to hit the road!


Important: The arms need to be set up so that the storage rod is on the outside of the arm. Otherwise, the tow bar could be damaged when taking turns.


Extra-Long Arms Get You Around Tight Turns

The SD's arms are longer than average, giving you an above-average turning radius. You're going to be able to get around obstacles and make sharp turns with no worry of clipping the corner of your RV. Maneuver through gas stations and the campsite no problem.


Built-In Rise/Drop

It's important that your tow bar is as level as possible while you're flat towing, with no more than a 3" difference between where the tow bar sits in the hitch receiver and where the arms meet the base plate. It's fairly common for the hitch on an RV to sit too high in comparison to the toad, making it necessary to buy a high-low adapter.


etrailer SD Tow Bar Built-In Rise/Drop

With etrailer tow bars, the rise/drop is built right in, so it's less likely that you'll need an extra adapter. The head joint is also able to tilt up and down so you can make the tow bar level for your particular setup.


Non-Binding for Easy Disconnect

Uneven ground and sharp angles can put the arms of the tow bar in a bind and make them stiff and immoveable. Once you get to your destination, the last thing you need is to spend several minutes wrestling, yanking, and kicking at them to get your car disconnected.


etrailer SD Tow Bar Non-Binding Lever

Instead, get out of a bind in one easy step. Simply give the trigger on the arm of the SD a squeeze to disengage the internal latch. This releases the pent-up pressure so you can unhook and get on with your adventure.


Each trigger release latch is positioned on the side of the tow bar arm. This allows for a comfortable yet firm grip, unlike latches that are positioned on the tops of tow bar arms, which can be difficult to grab. This out-of-the-way placement also creates a clean look for the tow bar.


Organized Setup: Integrated Safety Cables

etrailer SD Tow Bar Integrated Safety Cables

Two straight, vinyl-coated safety cables are integrated right into this tow bar, keeping them from dragging on the ground and getting damaged. They won't get lost or tangled either; your whole setup will be streamlined and organized.


These cables, required by law, will keep your toad behind your RV if there's ever an accidental disconnect while you're towing. The steel S-hooks on each end of the cables connect to the toad's base plate and the RV's trailer hitch, with spring-loaded latches to ensure that they stay connected.


The etrailer safety cables are rated at 14,000 lbs, regardless of the rating of the tow bar. While it's not necessary to have such a high rating, it's nice to know that in the event of an emergency disconnect, these heavy-duty cables will be more than capable of catching your vehicle. If all else fails, these safety cables won't.


etrailer SD Tow Bar Storage Rod for Coiled 7-Way Electrical Cord

The tow bar also offers a convenient storage rod for securing your coiled electrical cord (sold separately). The rod holds your power cord neatly out of the way and up off the ground.


Ridiculously Easy Storage

etrailer SD Tow Bar Storage

The etrailer SD is incredibly easy to store on the back of your RV. Most RV-mounted tow bars require you to lift the heavy arms all the way up; they have to be fully vertical before you can secure them in the stowed position. With etrailer tow bars, all you have to do is raise the arms an inch or two - which you probably would do anyway while unhooking - and swing them to either side. When you lower them down again, the locking pin will automatically slide into the built-in tab. They can store to the left, right, or with one arm each way, however is convenient for you.


etrailer Technical Support

At etrailer, we're committed to the products we sell, and to helping our neighbors journey. We don't just sell it; we've installed it, we've wired it, and we've towed with it, so you're getting your answers straight from the experts. Our etrailer technicians perform flat tow installations on a daily basis, so they know all about your tow bar firsthand. For the life of your tow bar, our experienced and knowledgeable staff are available via phone, email, and chat to help you with any questions or concerns.


What You Need to Flat Tow

Flat towing can be a much more convenient way to take your car RVing with you than using a trailer or a tow dolly. It'll save you storage space both at home and at the campsite, and it takes less time and hassle to hook up.


To flat tow your vehicle, there are 5 basic components you're going to need: a tow bar, a base plate kit, a safety cable set, tow bar wiring, and a flat tow braking system.


For the RV Between the RV and Towed Car For the Towed Car
Hitch Tow bar Base plate
Wiring plug Safety cables Braking system
Wiring adapter cord Wiring kit/diodes

The custom-fit base plate installs on the frame of your toad so you can connect the car to your RV with a tow bar. Hook up safety cables between the vehicles to ensure that the toad does not separate from the motorhome if the tow bar becomes detached. Tow bar wiring syncs your vehicle's signal lights with your motorhome's tail lights, as required by law in most states. Finally, the flat tow braking system - also required in most states - activates the brakes in the toad when you hit the brakes in the RV, making for smoother, safer braking, and preventing wear on your motorhome.

  • Does The Rampage Rock Rage Bumper Have Add-On D-Rings And What Is Needed To Flat Tow A 1999 Jeep TJ
    The Rampage Rock Rage Front Bumper for Jeep # RA97801 doesn't have a D-ring add-on option so you'd have to have a qualified fabricator weld D-rings in to the bumper if you wanted them. You'd also need to have that fabricator ensure that the bumper is properly secured enough to the frame to be able to tow from the D-rings. If you end up being able to tow from the D-rings then you'll want either the Roadmaster # RM-035 (3/4" thick D-rings) or RM-035-1 (1" thick D-rings) and a Roadmaster...

  • Recommended Flat Tow Setup For A 2024 Ford Maverick Hybrid
    Hello Robert. For flat towing your new 2024 Ford maverick Hybrid I recommend the Roadmaster Direct-Connect Base Plate Kit # RM97RR.

  • Will 2014 Jeep Grand Cherokee Summit Require Brake Light Relay Kit
    Hi Patrick; the # RM-88400 is not required for your Patriot 2 or the Hopkins # HM59VR. It is necessary on some vehicles depending on the braking system, but not on your 2014 Grand Cherokee. You will also need a base plate kit # RM-521440-5, tow bar # e74ZR (includes safety cables), and possibly a high-low adapter to complete your setup. If you use the etrailer tow bar it has a built-in rise/drop of 1-1/2" so an adapter may not be necessary. I went ahead and attached a help article below...

    Hey Ken, you are definitely on the right track for parts needed to flat tow your 2020 Ford Escape Hybrid.

    Hi Juan, You'll want to double check your owner's manual to confirm that your specific model can be flat towed first.
