I'm not sure I'm understanding your post.
1st, make sure you are completely level before you do anything related to truck, hitch or trailer. I go to a flat parking lot at a nearby school.
2nd, you want your trailer to be slightly nose down when its hooked up to the truck. That provides you with a higher tongue weight.
3rd, you want the front of your truck to drop at least slightly (not sure exactly how much Anderson wants) when you engage your WDH hitch.
Sounds to me like you need to lower your hall mount a little more so that you load more weight on to your tongue.
