Ok so who' s the expert/knowledgeable person on this subject as Im hearing different opinions....I read this on another forum "You got a least a ton, and maybe up to 3-4 tons hanging by two chains designed to pull not push so unless you keep tension on the chains via the trailer brakes you've lost all control of where that trailer is going to go. The brake controller acts with the TV's brakes and doesn't put the tension needed on the chains to keep the trailer straight and behind the TV.We've had 3 breakaways make the news here in upstate NY this week and all three destroyed the trailers and one the TV as well. I'll bet the farm all three of them had the breakaways set up like you want it or else didn't even have one. According to police reports none of the three disconnected from the safety chains. So much for bringing the trailer to a safe stop using the brake controller."
