Ok, this is my first post and I hope this is not looked at as a stupid question. I have a 2012 F250 PSD with the build in brake control box. How well does this one work and should it be replaced with ...
My experience with the 2005 version of the Ford brake controller is that it's the best controller I have ever used. Your trailer is in no way too large for it, I think it's rated to 4 axles. My previous controller was a Tekonsha Prodigy, a highly regarded controller, and the Ford was head and shoulders better.
