Brake Controller for 2012 Chevy Silverado to Double Tow

Question:

I live in Utah where it is legal to pull double trailers. I have a 2012 Chevrolet Silverado. It has a factory brake controller already installed. If i was to pull my flat bed trailer behind my camp trailer, can I use this brake controller to control the brakes on the flat bed? My camper has a 7 pin on the back for it to plug into. Not sure if the signal that the factory controller would interfere with the Echo brake controller or not?

The Curt Echo Mobile Trailer Brake Controller # C51180 will override the factory brake controller of your 2012 Chevy Silverado when you plug it into your truck, and you can use it to double tow so long as you have no more than four brake assemblies (meaning both of your trailers are single axle) and the brakes from your flatbed and camper are connected. You will not be able to use it by installing it onto your camper's 7-way to control the brakes from your flatbed, it would need to plug into your Silverado's 7-way and would be able to brake no more than four brake assemblies.

To do this you will want to use 7-Way Molded Trailer Plug with Junction Box # 277-000141 on your flatbed, using 10 Gauge Wire # 10-1-1 to run from the junction box to your brakes. On the rear of your camper you are going to want to use 7-Pole and 4-Pole Trailer Connector Sockets w/ Mounting Bracket and Wiring # HM40975-11998 as a way to connect the two trailers. This will work with the Echo so long as your trailers are each single axle.

If you have more than two axles and thus four brake assemblies I highly recommend using the Tekonsha Prodigy P3 Trailer Brake Controller # 90195 to replace your Silverado's factory controller because it will work with up to four axles (eight brake assemblies) and has storable settings for pulling more than one trailer and an easy-to-use LCD display that tells you immediately if there is any issue with your trailer wiring that would cause an issue with the controller's functionality.

I have added links to video reviews as well as a help article on installing a brake controller in your generation of Silverado which I strongly recommend reading.
