Built-in LED Light Strips

Integrated LEDs

This sleek and simple all-terrain tow bar has integrated LED lights that turn on and off with your RV's tail lights. Not only do these amber lights make the tow bar stand out, but they also illuminate the area between your RV and your towed vehicle to make it more visible as you travel at night. These lights also make it easy to hook up and disconnect your towed vehicle in the dark. No extra steps are needed to power on the lights. Simply plug the included power cord into your RV's 7-way plug as you normally would, and the lights will turn on when you turn on your RV's tail lights.


Superior Design for Sturdy, Lightweight Tow Bar

Unique Eggshell Design

The unique, eggshell design of the Nighthawk distributes stress evenly throughout its aluminum body, resulting in a lightweight yet durable tow bar. Critical points are made even stronger to allow for an 8,000-lb capacity. For example, the shank portion that slides into the hitch is constructed of steel to ensure that the tow bar can handle stress at this point. Stainless steel inner arms provide even more durability and strength.


Fast, Easy Hookup

The Nighthawk tow bar has a larger hookup radius than previous models to ensure simple, secure hookup. What this means is that, even if your towed car is not perfectly aligned with your RV, you will still be able to make the necessary connections. To achieve this, the Nighthawk has stainless steel, telescopic inner arms that adjust independently. In addition, these arms are able to pivot in and out, changing the spread. So, if your car is angled a bit behind your RV, you'll still be able to hook up by bringing the arms closer together and staggering the length so that 1 arm is longer than the other, allowing it to reach the more distant base plate.


The fact that the arms are extra-long also allows for a better turning radius. By putting more distance between your motor home and your towed car, your entire setup will become easier to maneuver so that your towed car will track behind your motor home without running the risk of hitting your RV during turns.


Triple-Lug Connection

No Quick Disconnect Bar

In order to be compatible with Blue Ox base plates, there are sturdy brackets at the end of each tow bar arm. These brackets attach to the base plates using 2 easy-to-access pins and provide a tight, stable connection for a safer and more dependable towing experience.


Non-Binding for Simple Disconnect

Freedom Latch

The Freedom Latch makes disconnecting this tow bar a breeze. This latch makes it easy to release the tension that can build up in a telescoping arm when the RV and towed car are not perfectly lined up. Just flip the latch to release the pressure, and the arms will be able to telescope freely, making it easy to disconnect the tow bar from the base plates. This allows you to disconnect even when you're at a hard angle or out of level.


Built-In Cable Guides

Tow Bar Cord Channels

The coiled ends of the included power cord and safety cables easily extend to your RV without dragging on the road. But coiled cords and cables can get easily tangled, creating a hassle and a potential hazard.


Power Cord and Safety Cables

This is why the Nighthawk's power cord and safety cables are straight on the ends that run through the tow bar and connect to your towed vehicle. This way the cables can easily be run through the Nighthawk's integrated routing channels to keep them from getting tangled. These convenient cable guides also keep the cords up and out of the way to create an attractive, streamlined appearance for your towing setup.


Superior Testing Ensures Excellent Quality

FEA test

This Nighthawk tow bar has been subjected to rigorous physical and computerized testing to ensure that it meets Roadmaster's exceptionally high standards. Throughout the design process, Finite Elemental Analysis (FEA) is done. Each of these tests display a 3-dimensional image of the tow bar while it is put under thousands of pounds of pressure. Areas of stress in the tow bar can then be located and studied so that those areas can be strengthened. This process is repeated until any weak spots, particularly those found in load-bearing components, are completely removed. The result is a durable, strong, and safe product.


Simple, Secure Storage

The Nighthawk can easily be folded up and stored on the back of your RV when it's not in use.


Secure Storage

After disconnecting the tow bar from your towed vehicle, push the arms of the tow bar together so that they are side by side. Fold the tow bar up toward the RV and the storage latch will automatically lock it in place.


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.


FlatTowing Components

The tow bar links your towed car to your motor home. 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 motor home in the event that your tow bar becomes detached. Tow bar wiring allows your towed vehicle's signal lights to sync up with your motor home'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 motor home are activated, preventing wear on the motor home and decreasing braking distance for your entire setup.

Roadmaster Nighthawk All Terrain, Non-Binding Tow Bar for Blue Ox Base Plates - RV Mount - 8K - RM-677

Average Customer Rating:  4.8 out of 5 stars   (399 Customer Reviews)

This sleek, aluminum tow bar is designed for use with Blue Ox base plates. LEDs line the arms for maximum visibility. A large hookup radius and hassle-free latches make it easy to connect and release. Safety cables and wiring included.

by:

Bought the Roadmaster for a Blue Ox base plate. Perfect fit. Would be 5 stars for the product but gave it 4 stars for the packaging. Theis is a heavy item and the box is merely taped -- not stapled! Unsurprisingly, the box arrived completely open. That I can tell, nothing is missing but can't be certain until everything is put together. However, this could have easily gone the other way with missing items (and the ensuing hassle to get things corrected). To Roadmaster: USE STAPLES! To etrailer: Tape it better!




by:

Love the LED lights and increased visibility. Easy to install; easy to use every time we move our MH! Love the way eTrailer follows up on the sale.




by:

Works great no binding lights make it visible for added safety at night




by:

I waited four months to install my tow setup because of COVID and it was worth it. The bar lets everyone on the road know the car is in tow and it is easy to hook and unhook regardless of the angle. The only problem is that the lights on the bar can overpower the night vision of the back up camera on our coach, but you don't back up when towing anyway.




by:

Great hitch. Had a safety recall but the parts were shipped quickly.




by:

No regrets in buying this upgraded model.
Works as well in the real world as the sales video claims.
I had to make a 7 point turn in my 40 foot RV. Disconnect and reconnect only took me 5 minutes.

I used this driving over 4000 miles in 2 months. This towed like a dream the whole time. It never bound up. I was never in a position where I couldn't disconnect or connect, even in state parks.




by:

Very well made. No bind to the extensions, and they have solid feel and a positive lock. The cable management system and lighting are are very helpful. Highly recommend this bar!




by:

This towbar has performed perfectly. Towing a 2020 Jeep Wrangler.




by:

The towbar arrived in an old box whith holes covered by tape.
The towbar was ok.
The unit was not what I thought I had ordered and the process to return it was quick and efficient.
No hassle except waiting 27 minutes on the phone for support is a little rude.




by:

I've owned 3 tow bars, this is by far the best I've purchased




by:

Heavy duty easy to use. The best tow bar that I've owned.




by:

Well built, easy to connect & disconnect by myself.
I am glad I spent a little more for a high quality product!




by:

Cover is of good quality, heavy gauge vinyl, and fits the tow bars and cable very well.




by:

E trailer has been great in service and delivery. Actually delivered ahead of original delivery estimate.




by:

Tow bar came apart due to factory defect, factory replaced with new.




by:

Nice tow bar. So glad I chose the aluminum unit. Steel would have been too heavy for an old guy like me.




by:

works well, easy to use, folds up out of the way. No complaints. would buy again




by:

Received in a damaged box . Box had been patched and taped up at etrailer before shipping. Parts missing.

Just upgraded from the Falcon to the Nighthawk. Hoping to get the same great service from it.




by:

Love it...changing over from 1 yr old competitor product that failed...




by:

The folks that designed this tow bar must have lots of experience hooking up and removing tow vehicles! Nice not to have to store safety cables and electrical wiring separately!!!




by:

What can I say, The Nighthawk is a top shelf tow bar. I love that it come complete with safety cables, wiring harness including the towed car side plug.




by:

I have purchased many Roadmaster products and they are generally well made. This unit had some fit and finish issues and the light strips are attached with adhesive and black silicon sealer. After having difficulty getting functionality in the wiring between the RV and towed vehicle and extensive testing the ground wire in the Roadmaster cable harness was bad. I called eTrailer as they are always very helpful/knowledgeable. In this instance they advised Roadmaster prefers to handle and quality issues. Roadmaster technical assistance was excellent, but the only choice was to return the whole tow bar and have them fix it or have them send a replacement wire harness and install it myself. Not wanting to wait for two-way shipping and repair I opted to do the repair and they shipped me a replacement wire harness. When I disassembled the unit, it was apparent the ground wire had pulled out of the butt connector where the cable is split in the middle to splice in the LEDs along the sides.
After repair everything was functional. Hookup and release of the bars to the towed vehicle is quite easy. If the wiring was good to begin with this would probably merit 5 stars for ease of installation and 4 stars for value. I will follow up if there are any further issues.




by:

Really like this unit.

Easy to set up but have not used the product to tow yet
