Were it me, I would adjust to try to get the front truck axle as close to unloaded weight as possible and always had comfortable towing. That is the way I have done it for years and have never had a problem. I fully realize that is not what some manufacturers recommend but I want my headlight aim to be normal and not blinding other drivers at night, and I want my truck to handle just about like normal. A half inch at the front wheel well may well translate to several feet high down the road at night.
That is not what some manufacturers recommend however so do what you think is best for you. I cannot say that you should do as I do because each situation is a bit different. The size or strength of your WD bars, the size and strength of the trailers A frame, the type hitch etc. all contribute to the decision.
I would recommend that you read what your truck manufacturer says, read what other members here say, and then make up your mind on whether to add more WD to your hitch. Good luck. :)
