Do yourself a favor and have a professional headlight alignment procedure performed on your MH. There is no substitute for alignment equipment which attaches to the front lens and allows the technician to correctly "dial-in" the correct alignment/aiming settings.
I have a 2001 Discovery and love night driving. I experienced the problems you described about poor/inadequate headlight alignment. During my yearly Pa. MH inspection I paid a extra $15.00 and had the mechanic perform the alignment procedure with "professional grade equipment". The difference was remarkable. My light beams now converge on the road ahead and light the road like they were designed to do. It's a pleasure to "night drive" and do it safely. I've just completed my 1100 mile trek from Pa. to Fl. and did 90% of the journey after dark. The headlights worked perfectly.
