A long time ago, maybe on this site, there was gent that was also having low quality light from his headlights on his M/H too. Well, he took it upon himself to do some serious changes to improve his lighting situation. Long story short, he changed his entire headlight assemblies from standard bulb/headlight bucket/housing, to a "PROJECTOR BEAM HID SYSTEM".
While it was a bit of work, the outcome was seriously better than any stock headlight (other than those using that technology already) assembly. He did a bit of body work etc. to accommodate the mounting system and, the close fit so that they looked like they were factory installed.
He supplied pictures of the entire process while the work was being done. When completed, he displayed the light patterns and brightness of the stock head lights and then, he did the same with the new Projector beams and it was phenomenal the difference. And, just as they do on the vehicles they come with from the factory, they had horizontal "cutoff" lines where they simply ZERO light above a certain height.
I do a fair amount of driving at night and I'd sure like to do that to our coach. Anyway, just a thought for you innovative types out there.
