Hey Phillip, thanks for reaching out!
The Curt Echo Wireless Brake Controller # C51180 will work with up to two axle trailers. Since you need more than that I recommend picking up the Curt Echo In-Line # C79DR instead.
I actually like this controller better than the original Echo because it installs in-line with the 7-Way on your vehicle, so you don't have to remember to grab and store it when you aren't towing.
The In-Line uses the same app system that the original Echo does so when it comes to operations it will be identical - this controller is just able to work with more axles.
Be sure to pick up the Manual Button # C83HR so you can have a hands-free towing experience once you initially get the trailer brakes set to the power you're wanting.
What do you plan on using this to tow?
