Features to know about

Know Exactly When Your Towed Car’s Brakes Are Active: Direct Brake Pedal Monitoring

When you’re towing, it’s important to know that your supplemental braking system is doing its job. The Roadmaster Stop Light Switch Kit activates your RV’s monitoring system whenever the towed car’s brake pedal is actually pressed. Unlike systems that only sense air cylinder movement, this kit gives you true pedal feedback so you can immediately see that the brakes are being applied and working properly. That peace of mind helps prevent towing with a misaligned or malfunctioning brake system.

Protects Against Brake Damage: Confirms Proper System Operation

Improperly installed or constantly engaged braking systems can cause serious wear or damage to your towed vehicle’s tires and brake components. This kit helps you avoid that by showing exactly when the pedal is being depressed. If the system happens to press on the brake when it shouldn’t, you’ll know right away. That means you can fix the problem before it leads to costly repairs. It’s a simple safeguard that helps keep your setup safe and your towed vehicle in good condition.

Constant, Reliable Power: Wired for Steady Performance

The kit wires directly into your towed car’s fuse box for a constant current supply and dependable 12-volt operation. That steady power ensures consistent monitoring signals every time the brakes are applied. For setups that don’t have a “tow” ignition position, this direct wiring keeps the system active and accurate without interruption. Once installed, it just works whenever you need it—no extra switches or complicated connections to manage.

Straightforward Fit and Setup: Designed for Easy Adjustment

Users mention that the kit fits well and the included instructions make it easy to install. The parts align cleanly and can be padded or slightly adjusted where needed for the perfect fit. Once in place, it becomes a low-maintenance part of your towing setup that quietly does its job trip after trip.

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.

I have ordered many products from etrailer and their customer service is 12 on a scale of 1 to 10. I ordered my products on the weekend and they were delivered on a Wed. I also later found cheaper prices on a few of the items and submitted the info for the 110% lower price guarantee and received the refund within a few hours. These folks are just plain great!

    I do have a base plate kit that is compatible with your 2016 Chevrolet Colorado Z71 Trail Boss but the Roadmaster EZ5 Base Plate Kit part # RM-523182-5 is not a confirmed fit for the Z71 Trail Boss package. For a base plate kit that is compatible with your vehicle, I recommend using the Blue Ox Base Plate Kit part # BX1721 as this is the only base plate kit we have list as a fit with the Z71 and Trail Boss packages.

    Before you purchase the necessary components needed to flat-tow your 2018 Chevrolet Colorado ZR2 behind your 2014 Tiffin Allegro Open Road 36LA you will want to review the "Recreational Towing" section of your owner's manual for any special clauses.

  • Does The Curt TriFlex NEXT Brake Controller Need Extra Wiring On A 2016 Chevy Colorado?
    Hello Brenson , Thanks for writing in. The Curt TriFlex NEXT Brake Controller # C67PQ will work on your 2016 Chevy Colorado, but it is not plug-and-play on that truck. The Colorado does not have a factory brake controller port under the dash, which is why there is not a custom wiring adapter available for it. The # C67PQ comes with a universal pigtail harness, so you will need to hardwire the controller into the truck’s wiring for power, ground, brake output, and the stoplight switch...

  • Is There A Plug-And-Play Brake Controller Wire Harness For A 2018 GMC Canyon
    There is not a plug-and-play style connector for an aftermarket brake controller for a 2018 GMC Canyon so you would have to splice into the factory wiring. You'll need to look for the cold side of the brake light switch by checking the wires coming off of the brake pedal with a tester # PTW2993. The wire that lights up only when the brake pedal is depressed is your brake light switch wire. If you can't find it or the wire is too thin of a gauge to splice into then you can use the Roadmaster...

  • Parts Needed to Flat Tow 2022 Chevy Colorado ZR2 Behind Motorhome
    We'd be happy to help with that. As long as your Colorado has a transfer case that has a Neutral and a 4 wheel low position, it can indeed be flat towed. For base plates, I'd recommend the Roadmaster Direct Connect base plate kit, part # RM78VR which Roadmaster confirms is compatible with the ZR2 package. For a tow bar, I'd recommend the Roadmaster Falcon All-Terrain tow bar, part # RM-522. You'll also need # RM-643 safety cables. To wire the taillights, use the # RM-152-98146-7 diode...

    I took a look at the owner's manual of a 2016 Chevy Colorado and a four wheel drive model can be towed so long as it has a N (neutral) and Four-Wheel Drive Low setting. There are a number of parts you're going to need in order to do this, starting with compatible base plates. I recommend the Blue Ox # BLU93FR. For a tow bar I recommend going with the Blue Ox Alpha # BX7380 because of how easy the tow bar is to connect to the base plates, the long arms that make it easier to maneuver when...

  • Comparing The Blue Ox And Curt Baseplate For A 2021 GMC Canyon
    The Curt Custom Base Plate Kit # C88FR is going to sit higher than the Blue Ox # BLU93FR, as well as all of the other options available so it's really going to come down to your personal preference and the brand of tow bar you chose. Both the Blue Ox and Curt baseplates are going to be compatible with Blue Ox tow bars so the Blue Ox Alpha 2 Non-Binding Tow Bar # BX7380 you purchased will be compatible with both. I personally prefer the Blue Ox since it sits lower and would look better with...

    Don't stagger, you've got this! To flat tow your 2020 Colorado behind your motorhome, you'll need a tow bar, base plates, safety cables, a wiring solution so the dinghy's taillights work along with those of the motorhome, a supplemental braking system and possibly a high/low adapter. For a tow bar, I really like the Falcon All-Terrain, part # RM-522. The non binding design allows you to release the arms of the tow bar from the vehicle regardless of how level the ground is.

  • Is it Possible to Tow a 2WD 2016 GMC Canyon?
    The owner's manual of your 2016 GMC Canyon specifies that the two-wheel drive version of this vehicle cannot be flat-towed, and the only way to tow it at all would be to use a tow dolly and have it mounted by the rear wheels. However, the tow dolly's we carry state not to tow vehicles by their rear wheels. There is a possible solution for you though, requiring either the installation of a lube pump kit if your Canyon has an automatic transmission, or a drive shaft disconnect if it is...

  • Roadmaster Stop Light Switch Kit for 2021 Chevrolet Colorado
    Hey Tim! The Roadmaster Stop Light Switch Kit # RM-751472 has the correct bracket for your 2021 Colorado. You will need this for the indicator light to function properly. The brake system still pulls power, so you will also want to add a charge line kit # RM-156-25. I'm not entirely sure which version of their disconnect you have since it's coming off a 2012, but more than likely it will work for this setup. Where are you headed once you get the new Colorado set up for towing?
