If you go to the 2nd link, then you will putting more weight on the steering axle, a little more on the trailer axle, and taking some weight off of the truck axle. Going to the 2nd link depends on how much weight you have distributed on the 1st link. That is where a weigh-in with your truck, with and without the trailer, would give you an idea of how your WDH is currently set up. Fender measurements would also give you an idea of how your WDH is setup. If your WDH is setup properly on 1 link, then going to the 2nd link would not be beneficial, and could actually put too much weight on your steering axle.
