Easy to install with OEM wiring harness, works great with each trailer I have pulled regardless of weight.

I have only used this once. It is easy to install, adjust, and works great. I would reccommend it. I don't pull anything crazy heavy, but this controller will work for anything my '04 duramax can get down the road.
