Just bought a new 30'Classic and a Prodigy controller (yes it is recommended by A/S and Tekonsha states it is a new model that is compatible with the actibrake system). Works fine. I, too, had a 'hot' brake smell the first outing, which I contributed to new brakes and the fact that I was experimenting with different boost settings. Tires and brake discs were no hotter than the tires/brakes on my truck. Next trip was fine, no fooling with the controller, no smell.
Fully retired now!
Never start anything before noon and always plan on being finished by 5.
I will never HAVE to be anywhere ever again!
