You WDH is not setup correctly, you can tell by the picture and the angle of the hitch, also sounds like it's only made for half the weight your using it with. I've used a Curt #17500 and it levels the Raptor and Trailer nicely. Also, validate your weights, you're getting close to the maximum on the Raptor, need to scale your trailer, and ensure you're weights are accurate. https://www.etrailer.com/faq-how-to-determine-trailer-tongue-weight.aspx
