Towing with Auto Leveling

Yes you still need the weight distribution. Although it may sound like your goal is to get the vehicle to sit more level, that's really just an artifact of the real purpose, a measurable artifact of what it's really doing. This is how we measure if the weight distribution is setup correctly. The real purpose of weight distribution is to transfer weight from the rear axle to the front axle. Why is this important? Because if you don't have enough weight on your front axle then you can't steer. That's a very scary situation. Keep in mind that this will be exaggerated even more when dragging all that weight up hill. It also may tow fine on dry roads because it has just enough weight on the front axle but you'll find out in wet or icy conditions, the tiny bit of weight you have left will not be enough to steer the gross combination weight of the truck and trailer.
