On my F250 I adjusted the controller to the point where it locked up the trailer at parking lot speeds, then down a couple notches. I personally like to feel the trailer drag on the truck a little, but I believe the perfect adjustment is when the trailer is neither pulling on the truck while braking or pushing.
I also check the adjustment when conditions change like rain, gravel, etc.
The trailer brakes are inferior to the ones on the truck, so I wouldn't adjust in a way that causes the trailer brakes to work harder. I agree that one shouldn't feel any push or drag from the trailer.
There is no need to adjust for road conditions because you do that automatically by applying the brakes lightly when traction is less. That is the beauty of the integrated controllers, aftermarket units don't have a clue what the driver wants to do.
