Hensley Arrow question.

I have found a used (slightly) HA for $900. After fighting my trailer, buying a 3/4 ton Ram CTD, and then new tires, I figured why not spend another $900 to get this trailer to pull right. Yes my weights were all good, but the camper sits about 2 inches nose high. I think this is causing the truck to push some. Anyway, I have to get a longer drop to get the trailer down 2 more inches, as I'm already on the last holes for the WDH. With the Arrow, how do you adjust the height of it? If my truck is too tall with a standard drop and WDH, how can I expect it to hook directly into my receiver? Maybe Im missing something.
