Features to know about

Smooth Hookups and Releases: Self-Supporting, Non-Binding Arms

Hooking up your toad shouldn’t feel like a workout. The etrailer SD Non-Binding Tow Bar uses self-supporting, telescoping arms that hold their own weight, so you can connect one side at a time without wrestling the bar to the ground. Once you pull forward, the arms automatically lock into place for towing. When it’s time to unhook, the non-binding levers release internal tension with a squeeze—even on uneven ground—so you can disconnect without the jerking or rocking that other bars can cause.

Built to Handle Tight Turns: Extra-Long Arms for Better Clearance

Tight corners at gas stations or campsites are easier to manage with these extra-long arms, which extend from 39-1/4" to 51-3/4". The added length gives your setup a wider turning radius and more clearance between your RV and toad, reducing stress during sharp maneuvers. Whether you’re pulling through a narrow site or making a U-turn on the road, the longer reach helps keep everything smooth and steady.

Keeps Things Level: Built-In Rise/Drop and Tilting Head

Getting your tow bar level doesn’t have to mean adding more parts. This one has a built-in 1-1/2" rise/drop and a head that tilts up or down 3", helping you stay within the recommended 3" of level between your vehicles. That built-in adjustment cuts down on the need for extra adapters and helps keep your towing setup balanced and safe from unnecessary strain.

Cables and Storage Already Sorted: Integrated Safety Cables

Straight, vinyl-coated safety cables rated at 14,000 lbs are built right into the tow bar. They stay up off the ground where they belong and won’t drag, tangle, or get misplaced. The built-in storage rod also keeps your coiled electrical cord (sold separately) neat and out of the way. It’s a clean, organized setup that keeps your gear secure and ready to roll.

Quick, Compact Storage: Arms Swing and Lock in Place

When the trip’s done, storing the tow bar is just as easy. The arms swing to either side and automatically lock in place when lowered, so you don’t have to lift and wrestle them upright. You can store both to one side or one each way—whatever fits your space best. It’s a simple design that keeps the back of your RV tidy while your tow bar stays ready for the next leg of the journey.

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.

by:

I've used it three times, and it's been great. Easy and quick to hook up, and unhook, to my Ford Escape Hybrid. I like the way it stores up against the motorhome. All the good things they said about it on this website were true!



by:

I like it being all steel makes it heavy makes and steady. The Blue ox adapters have more play in them the original Blue ox tow bar that failed on me. Overall seems like a great towbar



by:

super fast delivery! excellent customer service thanks!



by:

Very happy with tow bar. Pulls my toad perfectly and is a convenient quick hook up and unhook for ease of use.



by:

The etrailer XD non-binding tow bar is and Excellent product. I received it a few days after placing the order with Sara R. At trailer. She was very knowledgeable about what all the equipment that I had ordered for my setup. Thank you Sara.



by:

Works well and tows tight. Easy connection and disconnection. We can hook up our Wrangler in 5min.



by:

Easy to use and I like the way it stows. Also the safety cable hangers on the arms are a very nice touch, no dragging safety cables



by:

I purchased parts to turn my 2007 Minni Cooper into a toad. After selecting the items I was able to have an initial conversation to verify I had selected the correct parts. I had a few questions along the way and there were a couple pins missing from one item. All these conversations were super helpful and I achieved a perfect install. Thanks to the etrailer team. Best customer service I’ve ever experienced. Especially in the last few years.



by:

Quality of tow bar and cover excellent. Received purchase on time and in excellent condition. Want to thank Sarah for her help on the phone with the order. This not the first time I've purchased from etrailer and have alway received outstanding service.



by:

Would have gave it a full 5 stars if it would have actually fit into the receiver. Tried both my extension receiver and the OEM 2 inch receiver. Would not budge. Had to grind off the powder coating and then some. Now I need to then repaint to prevent rusting. I would have returned this if I didn’t need it now. Better quality control is needed on the e trailer brand. Guess I know it won’t rattle, lol. Buy a mainstream brand.



by:

Fantastic- works like a dream



by:

The wiring kit for the tow base kit was very well engineered and works very well. The videos for installing the base plate we're awesome step by step process and was very easily accomplished by someone with just a wrench and a drill and a few tools.



by:

Everything was good except the fact that the tow bar would not go into the receiver as it was at its maximum 2-in Square and I'm not the only one that has this problem as others in our group have had the same issue.



by:

SO easy to hook up and use with our new Ford Maverick Hybrid



by:

Good design but poorly manufactured. Used on a single, multi-week trip: Bar stayed on the RV. Removed when we got home and the powder-coating has cracked and bar is showing rust inside and out. Chrome on extending arms is pitted and beginning to rust. Emailed etrailer but Cody informed me that I would have to ship it back at my expense without any commitment to replace! Disappointed with etrailer after years of previous purchases



by:

Outstanding product and even better customer service! Two backyard mechanics installed baseplate and braking system with just one call to confirm proper wire connection. Total package works great.



by:

About 5,000 miles on it so far and it works. Sometimes the quick release levers are hard to squeeze for 70+old hands. Same for the safety latch on the cables.



by:

One word. Fabulous! The SD tow bar is a superior product. I don't want to say bad things about the most popular tow bar out there, but etrailer SD is just better engineering. Watch the video for the product. My Roadmaster base plate was installed by Dave C. Of [company] with great expertise. See the pics



by:

I like it very much with the exception that getting the arms locked in is a little difficult for me. My previous tow bar locked in by moving forward and weaving left and right. This isn’t that easy. Once I got them locked in it worked flawlessly.



by:

This tow bar has given excellent service. I tow a jeep behind a motorhome. Easy to hook up. You don't have to be "exactly" in position. Safety cables are heavy with heavy hooks. No issues. All very good.



by:

This works great. Had a different one that was more expensive. It was harder to use. Highly recommend etrailer unit



by:

Excellent product, easy adjustment for height by flipping around. Had to get a longer break away cable for my rv/jeep but other than that, product has been great, tows my Jeep Wrangler with no issues.

by:

SO FAR IT WORKS GREAT, I PULL MY 2006 JEEP WRANGLER BEHIND MY CLASS C E 450. ITS VERY EASY TO HOOK UP AND UNHOOK.



by:

Bar has worked fine. The clevis ends attach to the rod with a single 3/8” bolt each, so only two little bolts attaching your up to 6000lb vehicle to your tow vehicle, seems excessively light, but it hasn’t broken yet…

According to Demco who manufactures the tow bar for us, the shear strength of the bolts you mention is more than adequate to handle the rated capacity of the tow bar, which is 6000 lbs.
