Features to know about

Do I Need a Braking System for Flat Towing?

A braking system is a must when towing a vehicle behind your motorhome. Without it, the extra weight of your toad (towed vehicle) puts more stress on your RV's brakes, makes it harder to stop safely, and can even put your warranties at risk. Most states legally require one, and if you're ever in an accident, not having a braking system could leave you with major insurance and liability problems. Plus, without one you don't have a breakaway safeguard. If your toad ever disconnects, there's nothing to bring it to a stop.

Pros of a Permanent System

With the RVi Shadow 2, you only have to install it once and that's it. No crawling around or extra setup every time you tow. Just connect the power cord at the front of your vehicle and the system fires right up. Plug in the Bullseye monitor inside your cab and you're ready to roll. While the components are installed permanently in your toad, they remain concealed and inconspicuous. None of them will interfere with normal driving, and most of the time they are not visible. Also, you don't have to find a place to store them between trips.

How Does the Curt RVi Shadow 2 Work?


Shadow 2 box

The RVi Shadow 2 uses an inertia sensor to activate. As your vehicle slows, the Shadow 2 senses the change in momentum of your toad. It precisely measures this change so it can activate your toad's brakes to match the rate of the RV's deceleration; this is what makes it proportional. When you apply the brakes in your motorhome, the Shadow 2 system will engage the brakes of the toad at the same time with the same amount of force. This keeps the RV and the toad in sync with each other, so from a gradual slow down at a red light to a hard stop in an emergency, the toad and the RV will brake together.


Note: The Shadow 2 box must be pointed in the direction of travel for the internal sensor to function properly. There are arrows on the unit to help ensure it is installed correctly.


Bullseye in hand, in-cab wireless controller

The in-cab wireless controller, called the Bullseye, lets you adjust the sensitivity of the inertia sensor to determine how hard the Shadow 2 will pull on the brake pedal. It's totally up to you how sensitive you want it to be; a heavier vehicle will probably need more sensitivity, while a lighter one doesn't need to brake so hard.


brake cylinder

When the Shadow 2 detects a change in inertia it activates the cylinder brake cable assembly and the toad's brake pedal is pulled. At the same time, the rings on the Bullseye monitor illuminate letting you know the system is actively braking your toad vehicle. The Bullseye monitor uses three rings to show braking force. A light tap on the brakes lights up the first ring, while harder stops illuminate two or all three rings.


brake cable on brake pedal

The cable portion of the cylinder brake cable assembly attaches permanently to the arm of your toad's brake pedal. Though it is permanent, it should not interfere with your everyday driving. In most vehicles, it is tucked up where you can't even see it.

Vacuum Pressure Creates Smooth Braking

When you're driving, your vehicle uses vacuum pressure to create the force needed to bring the car to a stop. On most vehicles, this vacuum-assist function does not work when the engine is off. As a result, a lot of supplemental braking systems have to use an excessive amount of pressure while braking the toad.


The Shadow 2, on the other hand, reactivates the vacuum-assist function by tying into your car's vacuum line. Your car will brake evenly and naturally as it's being towed, so there's less risk of damage.

Bulit In Safety Features


Breakaway switch with coil snap

The Shadow 2 also comes with a breakaway switch, an absolute must for safe flat towing. If there's ever an emergency situation where your toad becomes detached from the motorhome, the breakaway switch will immediately activate the brakes and bring the vehicle to a stop. This switch mounts to the front of your toad and wires into the Shadow 2 operating unit. It includes a snap clip that connects to your RV's hitch receiver with a breakaway cable. If the toad and RV become disconnected, the cable will pull the pin out of the switch and trigger the braking system.


Addtional safety features include 3 LED lights on the Shadow 2 box that provide specific information about the status of the breaking system, and visual and auditory alerts from the Bullseye monitor.

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.

The Shadow 2 fixed system made a good first impression. The control box and wiring harnesses just plug in to each other and the setup seems a bit more straightforward compared to other similar braking systems. The instructions included are well written and easy to follow. I also love the Bullseye monitor which is what really sets this system apart. It has a touch screen and it does all kinds of stuff like real time towing info, diagnostics and braking adjustment just to mention a few.

Dodge Charger

I recently got to host a first look for this system and I gotta say, its pretty cool. Once installed this system in out of sight out of mind. Compared to other permanent install, it's much more user friendly than most. The only thing you will have to install on the RV is a charge line if your RV doesn't have one. If it does, then congrats! One less step for your install. The bullseye is the hub for everything and will notify you if something goes wrong or needs your attention. The Shadow 2 also comes with a battery charger that you can also monitor from the Bullseye which is a really cool touchscreen monitor.



by:

We just got these added to the site, so I was really excited to go to the first look training so I can learn more. I really like that the RVi Shadow 2 is a one time install, no need to have to put a heavy unit in and out of the car every time you flat tow. The Bullseye screen that is included is super awesome! I love that it will alert you when things are not working properly, and it is always nice to have that manual override at arms reach in case an emergency were to happen.

  • Will Curt RVi Shadow 2 Braking System Work To Flat Tow 2023 Ford Maverick?
    Great question, Jeremy. The Shadow 2 brake system # RVI94FR is compatible with many hybrids, and the 2023 Ford Maverick uses electric boost or regular vacuum boost brakes, both of which are compatible with the Shadow 2. The only reason a vehicle wouldn't work with this system is if it used the rare hydroboost brake booster that ties into the steering pump hydraulic lines. Where do you plan on taking the Maverick for the next journey?

    Alex, pairing is required to get full functionality. The Bullseye monitor needs to be manually paired with your Shadow 2 brake system # RVI94FR during setup. It doesn’t arrive pre-paired, so you’ll want to leave the breakaway cable unplugged during the pairing process and select the serial number on the Bullseye’s screen.
