If you look at the back side of your headlight assemblies you will find two adjustment knobs. One moves the bulb/reflector side to side and the other moves them up and down.
They have limited travel and if you over tighten them they will break. Ask me how I know...

In my 05' Northern Star we had a similar issue but ours was because the headlamp assembly was mounted in a fiberglass mold that was mis-molded.
This mis-molding caused the headlamp assemblies to be tilted to far down (despite the adjustment knobs) to adjust the assemblies for reasonable lighting. I ended up having to modify the mountings to tilt the light assemblies further up to get them to show down the road further.
I also changed out my lighting to LED which helped immensely. Hope that helps.
