I've presented this scenario to a few folks and got varried responses. Let's try it here

I pull a 24 ft cargo trailer with electric brakes and a Tecnosha controller.

Simple part: Apply the brakes in the coach and the trailer brakes are applied.

I've been told by the trailer dealer that the trailer brakes work off the motorhome's brake lights. Makes sense, right?

I then noticed that when the engine retarder is engaged the coach brake lights come on. I asked the triler dealer if that means the trailer brakes are applied when the engine retarded is engaged. His response was "I would think so. If you are slowing the coach you want the trailer brakes to be applied as well." Makes sense too, right?

Now the big question is this. Does the coach know the difference between the brake lights and the hazzard flashers? Are my trailer brakes being pulsed with the flashers when I'm climbing a steep grade at 25 or 30 MPH?

Since I don't know the answer, I have been adjusting my brake controller to the off position when I have to use the flashers going up a hill. I get nervous when I have to use the flashers going down hill.

Your thoughts?
