TEKONSHA P3 Electronic Brake Controller with Plug & Play Wiring Harness for 92-08 Ford Vans & 94-96 Pickups - Trailer Towing Brake System for Safe RV & Boat Hauling

When used on it's most basic setting, the controller worked fine. I had issues with it when it was set on the various 'custom' trailer sizes. This includes once when it locked up one of the trailer brakes when the truck was at a standstill. No bueno.I also could never figure out how to store the settings, which is one of the special features of this model. I realize this is probably a user issue, but it goes to show it isn't very intuitive.Overall I should have saved some money and just gone with a more basic model.
