Ok, let me open a can of worms. I have ZERO experience hauling a vehicle on a dolly or a trailer so I'm looking to learn from other's experiences. I do have a fair amount of experience towing boats. Including hauling an oversized boat with an undersized truck from Maine to Florida. Plus hauling overloaded single axle utility trailers at times. What's worked for me when the ever-increasing sway kicked in was to slow down. Sway seems speed related. Sway that is sufficiently dampened and goes away after a second on it's own at 45mph can be out of control and try to take over at 55mph. So with this "fact" in mind, I've always responed to sway by removing my foot from the gas and holding the steering wheel straight. i.e. no radical braking or accelerating or steering corrections. I've read umpteen times on the internet that you should hit the gas to correct sway. This just doesn't sound right to me. You're adding more speed to a problem that is exasperated by speed. I've also read that you should manually activate the trailer brakes. That makes a lot more sense to me. Your thoughts?
