I would do my home work on the True Control. The shop I dealt with sells Hensley hitches and other Hensley items but will not sell the True Control. I talked with Andy at Hensley and he tried his best to get me to buy one at a pretty good price, but I went with Brake Smart on the advice of Zanetti's who install lotsa controllers and incidentally have done many Ford IBC retrofits. I will try to get a hold of them and ask them what their objections to it are. I remember that it had issues of some sort and in their opinion could not hold a candle to the Brake Smart especially with hydraulic brakes.
On edit, I got a hold of Kyle Zanetti and he said that their primary objection to the True Control is that if you bump the controller with your knee or in any other way, you have to re-calibrate it everytime. Not so with the Brake Smart. That and many other features which the Brake Smart has.
I don't sell them, I just like the hell outta mine!!
