For pickup truck owners only.
If you have the pickup truck on board trailer brake controller like the one shown below, have you found a method of using it to control the brakes on a towed vehicle such as a Jeep?
I know that this system works "out of the box" with my car hauler trailer which has electric brakes.
I wonder if it can be adapted to add an auxiliary vacuum pump mounted on the Jeep like the US Gear "Unified Tow Brake" system?
