Strong crosswinds or a passing semi can start your trailer rocking before you even feel it at the wheel. The Curt True Course Advanced Bluetooth Trailer Sway Control detects that side-to-side movement and automatically applies the trailer’s electric brakes to bring it back in line. It reacts in real time during emergency maneuvers, poor road conditions, or heavy wind so you stay steady and confident while towing.
Getting started doesn’t require rewiring or extra modules. Just mount the 11" long x 3-1/2" wide x 3-7/8" deep module level on the trailer frame, connect its 7-foot cord to your tow vehicle’s 7-way, and plug your trailer’s 7-way into the module. The built-in LED shows when the system is active and ready, so you know you’re protected before you hit the road.
The True Course is designed for trailers with 1 to 4 axles (2 to 8 brake assemblies) and is compatible with electric trailer brakes only. It functions independently of your brake controller, so it can be used with factory or aftermarket controllers and even alongside a weight distribution hitch if you already have one installed.
You can pair the True Course with the OneControl app to monitor sway events and system status from your phone. The app provides visual and audible alerts, and integrates with other OneControl products like the Echo brake controller (sold separately), so you can manage everything in one place.
This solid-state system is self-contained and sealed for outdoor use, built by CURT for safe, dependable towing performance. It includes a 1-year limited warranty for peace of mind every time you tow.

Awesome product
Super easy to install and great customer service.
Install was easy. A little hard to line up with the top since the top has a slight curve. Plugged into the truck and the green light comes on, so I guess it is working. Won't find out until I actually tow the trailer to see how it works. My one question would be why the green light stays on and blinks after I unplug the 7 pin connector from my truck. It did go off after I disconnected the battery from the RV.
I towed a loaded 5000 pound snowmobile trailer Normally a tractor trailer passing me would just move me all over the road. My Suburban and trailer instead stayed right on course. Would recommend this product. Also it was easy to install.

That definitely sounds like a peace of mind upgrade! I'm not too familiar with snowmobiles but they always look like a blast to drive. How long have you have been sledding for?

This is the third True Course unit I have purchased in the last few days. I have also purchased a Curt 7 pin tester. According to it, all circuits are working so the mystery remain unsolved as to why none of the three units had a working "Status" light. I have escalated directly to Curt/Lippert and hope to get resolved, but this may be some common issue among this particular product...

I'm sorry to hear you're having so many issues with the Curt True Course. I have a few questions to help determine what the issue may be. When you're getting everything set up is the True Course connecting to your app like it should? Have you driven around the block to see if after driving and braking the unit will shows any sort of a status light? I see you're also using the Curt Echo, when you have everything plugged in, have you used the manual override thru the app to send a signal to the unit? If there is no status light on the unit that usually means its in a sleep mode and needs a signal to wake up. Let me know what you find out when you can, or let me know what Curt tells you.
I received my sway control and have it installed on my travel trailer but have not had a chance to go camping yet. I talked to Josh at Etrailer before I ordered. He was very helpful and was the reason for my decision! If it works as well as advertised, I will be very satisfied with my order!
Unit did not work, had to contact Curt to get a new unit shipped to me.
Working great
I haven't been able to determine if I should connect true course first or the Bluetooth brake controller first. I'm also not sure if the device is actually working. When I turn on the app, the controller says connected, but does it stay connected when i close the app?

Thank you for your review, Nicholas! It shouldn't matter which device is connected first. When you say you're closing the app, are you fully closing or just minimizing the app? Also, have you been noticing any sway issues when your towing and or does it feel like your trailer/camper is pushing your tow vehicle when you are applying the brakes? I look forward to hearing back from you!
