Have Prodigy on both chev. duramax pickups and on motorhome. Can adjust so trailer brakes come on first and how much. Can adjust down to come on just right when using the jake brake on motor home. Brake lights come on when jake comes on. Can come off steep hills without use of brakes on motorhome and not heat up trailer brakes on low setting. No problems so far, used on one pickup now for 6 years, one pickup 2 years, and bus for 3 years.
