For those that have true proportional brake controllers (such as a Prodigy P2 http://www.tekonsha.com/content/pro...part=90885 ), you can help me preach to the uninitiated !!. These things are just fantastic. No more adjusting the controller for low speed (parking lots, gas stations) and then tweaking it for the highway. No more herky jerky at toll booths. Just nice, smooth brake action at any speed.
My first experience with these was after installing one on the KC Region tow van. Just a huge advantage. Now I have installed one on my tow van with the result that my formally PIA trailer brakes are WONDERFUL to live with. The P2 retails for about $155 but I grabbed a new one via a Google search for $100 shipped. WAY worth the money.
