Hooking up on uneven ground can turn into a wrestling match if the tow bar won’t cooperate. The self-supporting, telescoping arms on the etrailer SD hold their own weight so you can connect one side at a time without fighting gravity. Each arm extends, pivots, and tilts to line up with the base plate, then locks automatically when you pull forward. When it’s time to unhook, non-binding release levers let go with a squeeze, even if the ground isn’t level. The grip-friendly triggers sit on the side of each arm for a comfortable release every time.
Tight campground loops, fuel stops, and city corners get easier with longer arms. Extended to 51-3/4" from the hitch to the base plate, the SD gives your setup a wider turning radius. It tracks smoothly behind the RV and helps you clear obstacles without clipping corners. The added length also makes it easier to align when you’re backing or pulling forward to lock the arms.
Keeping the tow bar level protects both vehicles, and this one builds the correction right in. The shank offers a 1-1/2" rise or drop, and the head tilts an additional 3" up or down so you can stay within the recommended 3" of level. That means fewer extra parts and a cleaner setup. You get a safer, straighter pull and less stress on your connection points every mile down the road.
Two straight, vinyl-coated safety cables are built right into the bar and rated at 14,000 lbs. They stay up off the ground, won’t drag, and can’t be misplaced. Spring-loaded latches on the cable hooks keep them secure while towing. A built-in storage rod holds your electrical cord (sold separately) neatly out of the way, keeping your setup organized and tangle-free from hookup to storage.
When you’re done towing, stowing the SD takes almost no effort. Just raise the arms slightly, swing them left or right, and they lock themselves in place. Store both arms on one side or one on each—whatever clears your rear bumper best. The steel construction with E-coat finish resists corrosion, and when folded, the tow bar stays compact and secure on the back of your RV, ready for the next trip.
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.

Im still very pleased with our etrailer SD Non-Binding Tow Bar. It worked flawlessly in a trip up and down the East Coast earlier this year and were soon to give it an extended workout in a two-month Tour of America we have planned for September and October. I have no reason to expect anything but continued great performance from it.

The product was and is excellent. Everything functioned as it should and continues to do so. We have been towing our little Fiat behind our RV with no issues at all. Big shout out to Etrailer for their guidance and service!

We have used the e-trailer tow-bar for our TOAD 2016 Smart ForTwo equipped with the Blue Ox baseplate setup self-installed total of two times, both exceptionally easy drives. First was with our 24 Class C, SF Bay area to Pismo beach. Did not even know it was on the back in either direction, no difference in mileage TOAD is under 2000 pounds. Sold the RV, decided to move to Louisville traded Wine Country for Bourbon Country PLUS our 3 kids1 Grand Kid live there!!!. Had to “flip” the hitch over for the van. RV needed it ped down, van needed it up for clearance. Hitched it up behind our 01 Econoline van loaded to the gills and took 5 days driving to Kentucky. Couldnt be more pleased with the e-trailer tow bar and the Blue Ox kit...
