Did you get a picture of the front without the trailer?
It should go down when your trailer is hooked up if your WD hitch is setup correctly. If it stays the same, or goes up, then you need to put more torque on the WD hitch, which would also bring the rear up a bit, as it transfers weight to the front.
Looks good though, nice truck, and nice trailer!
