Sturdy, Built-to-Last Tow Bar

The heavy-duty etrailer XHD tow bar is tough and built to last. Sturdy, modular steel construction offers increased weight capacity and strength to pull up to 10,500 lbs. The XHD is perfect for towing a full-size truck or SUV. Two hitch pin holes allow you to position the tow bar closer to or further from your RV, without sacrificing load capacity.

The black powder coat finish protects against the elements and flying road debris. And stainless steel inner arms provide additional durability and allow for smooth operation. Quality-engineered pivot points and hardware ensure both strength and maneuverability.

Fast, Easy Hookup

With independent, easy-to-maneuver arms, the XHD makes connecting your towed vehicle to your motorhome a breeze. Unlike most tow bar arms that move together along a single plane, the XHD tow bar arms operate completely separately from one another. A vertical bolt through the head of the tow bar keeps the arms positioned one on top of the other, allowing for a more fluid hookup. The arms pivot horizontally on this bolt, allowing for an unlimited spread so that you can hook up to base plates with almost any spacing. A built-in joint at the base of each arm allows for vertical movement so that you don't have to tilt the entire head when positioning the arms.

The arms telescope for easy extension to your base plate connection points, even if your towed car is not perfectly aligned with your RV. The self-supporting design of the arms also allows you to telescope one arm out and attach it to the base plate without having to worry about supporting the opposite arm at the same time. The arms lock into place when you're ready to tow, and the extra length of the arms allows for a better turning radius. By putting more distance between your motorhome and your towed car, your entire setup will become easier to maneuver so that your towed car will track behind your motorhome without running the risk of hitting your RV during turns.

Base Plate Connection

In order to be compatible with Duncan base plates, sturdy adapter brackets are included for compatibility with the ends of each tow bar arm. These clevis-style ends attach to the base plates using the included hardware and provide a tight, stable connection for a safer and more dependable towing experience.

Non-Binding for Simple Disconnect

The built-in trigger releases make it easy to disconnect the XHD. Tension can build up in a telescoping arm when the RV and towed vehicle are not perfectly aligned. Engaging the trigger on each arm releases pressure and allows the arms to telescope freely, making it easy to disconnect the tow bar from the base plates, even if you are at a hard angle or out of level.

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 of the latches also creates a clean look for the tow bar.

Straight, Vinyl-Coated Safety Cables Included

Two straight, vinyl-coated safety cables provide added protection should the tow bar ever disconnect during towing. The cables are held off the ground by the included mounting clips. These clips keep the cables from dragging on the ground, preventing damage and tangling. Steel S-hooks with spring-loaded latches connect each cable to your towed vehicle's base plates and to your motorhome's trailer hitch.

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.

Versatile, Secure Storage

Independent arm movement also allows for storage versatility. Easily store the tow bar out of the way, alongside your RV. The arms can be folded up to the right or to the left, or you can fold one arm to each side so that they are parallel to your motorhome's bumper. Just pivot each arm into position and a peg at the base of the arm will snap into a built-in tab, latching the arm in place so that you don't have to worry about it coming unfolded during travel.

For added protection, slip on the etrailer tow bar cover (e99008 - sold separately) while the tow bar is folded up either to the left or the right against your RV.

Guide to Flat Towing

Flat towing your vehicle is much more convenient than using a trailer or a tow dolly. These other options take up much more storage space, leaving you less room both at home and at the campsite. In addition, securing your vehicle to a trailer or tow dolly can be a hassle and more time consuming than hooking up with a tow bar.

There are 5 basic components needed when flat towing a vehicle: a tow bar, a base plate kit, a safety cable set, tow bar wiring, and a supplemental braking system.

Towing Basics

The tow bar links your towed car to your motorhome. It attaches to the custom-fit base plates that install on the frame of your towed car. Safety cables ensure that your towed car does not separate from your motorhome in the event that your tow bar becomes detached. Tow bar wiring allows your towed vehicle's signal lights to sync up with your motorhome's tail lights, which is required by law in most states. Finally, the supplemental braking system - also required in most states - brakes your towed car when the brakes in your motorhome are activated, preventing wear on the motorhome and decreasing braking distance for your entire setup.

Video Transcript for Review of etrailer XHD Tow Bar - Hitch Mount Style - e57ZR

Jeff: Hello everybody. This is Jeff at Today we're going to take a look at this etrailer XHD two-inch RV Mount non-binding tow bar for the Duncan base plates has a 10,500 pound gross towing weight capacity. Now this tow bar will let you tow your vehicle safely and securely behind your motor home. The shank right here, it'll slide into your two inch trailer hitch receiver on your RV, and there's no bow mount necessary. If you notice on the shank also, they have two hitch pin holes are about two inches apart.

This allow you to position this tow bar, either closer to or further from your RV, depending on your application, without sacrificing any load capacity. You can see the pin and clip here this is included to attach this to your hitch receiver. Also there's no need for a high low adapter on most setups because this adjustable head on this tow bar will tilt up or down three inches to keep your tow bar parallel with the road during towing.And the shank if you notice back here, has this built in one and a half inch drop, or if you flip it over one and a half inch rise for additional height adjustability, the arms on these are telescopic self-supporting arms make for a fast, easy hookup. The main feature is the self-supporting of the arm. Basically these arms will fall to the ground when they're unfolded.

Some of your tow bar systems require to you try and balance both arms at the same time while trying to hook them up, this you could put the arm in whatever position you want and it'll stay right there. And just to show you, if we lift up on this arm and you get right there, you can let it go, hold this down it'll stay in that position. If you move it down a little bit, it'll stay just there. And again, if you want to raise it up some more, pick it up to the side you can see that it'll stay just like that.So they are, self-supporting very nice feature to have. They also offer full articulation, which means these arms could actually could be moved all the way out this way.

This one, all the way, this way. So you'd have 180 degrees of articulation, which allows for a nice unlimited spread to fit your application when you're hooking these arms up.It is a self-aligning design, basically you just hook up and then you drive your RV forward. And then what happens when you do that It'll pull the stainless steel inner arms out. They'll extend into a nice rigid tow-ready position. And then when you get far enough, you can hear that they'll automatically lock into place.

And you're all set up to ready to tow. They are a non-binding design, which allows for you to easily release your vehicle. Even if it's on unlevel ground, they have these trigger releases right here, one on each arm, that when you push down on that trigger release, it'll raise the arm and you can move the arm even if they're under pressure, just push that release down and then release the arm, very nice feature.Also, if you look on each arm, here's these integrated cable mounting clips. These will keep your included safety cables off the ground, prevent any dragging. And if you notice the cables, the whole length of the safety cable has a nice vinyl coating on it to protect it. And also on each end, they'll have these steel S hooks with the spring loaded latches here for added security. On this arm, you might notice this storage rod right here. This is a built-in storage rod, this will keep your coil, the electrical cord in place and off the ground. Now the electrical cord is not included. You would have to supply that, but when you do plug in your electrical cord and you have the coil there and it stretches out, you don't want to drag hanging down and possibly dragging. So you can take the extra coils, pull this clip, put the extra coils up on this rod, put the clip and it'll hold it up in place out and off the ground.Now this also offers a simple, secure storage alongside your motor home. These arms can be folded together, and then they both swing to the left and lock into place on these holes right here, swing to the right either way are, as I mentioned, you could swing one out this way. It locks in this one all the way out here. So there's multiple ways of storing them. Does have an E-coat finish on it provides a nice corrosion resistance. This part is made in the USA. This part number here is compatibility it works with the Duncan base plates. As you can see, it will include these Duncan adapters and the hardware to install them. Application it slides into a two inch by two inch trailer hitch receiver, weight capacity on this is 10,500 pounds. Now, one note I do want to mention is we also sell a tow bar that's a SD version.And when you look at both of them, they almost look identical, but the main differences, the SD is a lower tow bar. It's about 6,000 pound capacity this one is a 10,500 pounds. And the reason they get the higher capacity is if you look at that stainless steel arm, it is going to be a larger diameter on this XHD compared to the SD version. So that's how they'll get the higher capacity.Now, the weight on this whole tow bar is about 46 pounds, a few measurements if we push these arms together so that they're straight ahead. And we measure from the hitch pin hole here at the end of the shank to the base plate, pin hole center to center. When they're straight ahead, when they're retracted, like they are now is going to measure 39 and a quarter inches. If we extend those arms out all the way and they lock into place and then measure from that hitch pin hole back here to that, it's going to be 51 and three quarter inches. The distance from this hitch pin holes to where the shank starts to drop or rise right about here is going to be five and a half inches. And then from that hitch pin hole at the end of the shank to this vertical bolt in the head is about 12 and a half inches.It does come with this nice operator's manual. That'll describe how all these parts go together and how it operates. But that should do it for the review on the etrailer XHD two inch RV mount non-binding tow bar for the Duncan base plates has a 10,500 pound gross towing weight capacity.
