Tried a cheap 7 blade trailer tester but the truck didn't recognize the tester as a trailer when the brakes were applied though it seemed to work that way when the tester was first connected. So I bought this device and it recognizes the controller and applies the load. Now the truck recognizes the new tester as a trailer and I can test all functions including the brakes.
