Circled back to my buddy. First a bit of clarification, yes its a 2019 not a 2109.. LOL and yes it does have an integrated controller. He loaned it to a friend who put a heavier load on it, when it cam back the brakes worked just fine. I'm guessing since it was a new trailer it had something to do with the brakes getting a better ground with use, or the magnets getting worn in. Thanks for all the suggestions, this place is a wealth of knowledge!
