After having seen the Redarc installation I was sold. No way I could live with a brake controller sticking off the dash like that. I am taller than average though. My wife would not have approved either. There are also good controllers that mount on the trailer as well, so you don't have to worry about installing anything in the car. I do like the the redarc it is out of the way but easy to reach and see from the drivers seat and works better than the trailer mounted tekonsha unit we had.
