I’m doing this from my phone so forgive me. Just quickly looking from my minds eye at what your wheel well height is after applying the wdh, it seems right to me. Of course I’m not taking the weights into consideration.
Aside from that, to get the trailer a touch nose down you should be able to add (I think it’s add, but could be remove) a washer from the wdh head? Thereby tilting the ball back some and pitching the nose down.
Question is, how does it tow? If I have time tomorrow I’ll play with the numbers and come back (have a busy day at work lined up already) but you should also post it over on the keystone forum as well..those guys are typically on it hehe.
