My 3500HD allows you to set trailer brake bias by entering number 0-10 directly via the DIC. It can also be set using a manual slide switch on the ITBC.
The towing guide tells you how to find the correct setting (basically, while moving at slow speed (I think it is about 20mph), you move the manual slide switch until the trailer wheels lock, then back off slightly).
The guide also states that when towing a very heavy load, even max bias may not lock the trailer wheels.
Dually is not provided with sway control (I guess they figure its not needed with DRW).
Remember - trailer brake bias is road condition specific. Any time road conditions change, bias needs to be changed.
