The first thing I would do if I were you is, (and this is not meant to be derogatory) stop guessing at your available voltage at your present headlights. That is, go out and physically use a VOM and check to see just what you're getting before you run out and spend your hard earned money on what may be a futile effort.
I mean all this as a sort of educational experiment/test. This way, you'll know exactly what you're getting. Yes, it's quite possible there is a voltage drop which depends on all kinds of parameters. Many headlights are powered through the Headlight switch which, is wired with normally too small of wire.
And, as you are thinking, there could be EXTRA loom involved due to the wiring harness is used for many vehicles and much of it is not needed but, contributes to voltage loss over longer than needed runs.
And, not only all that but, in reality, the verdict is sorta still out on LED headlights. Yes, there are applications for many vehicles/trucks/motorcycles etc. But are the folks that have paid the high prices for what's being determined as "High Output" or, High Quality, really getting what they paid for?
I agree with you on the dim part, for sure. Our coach, an '04 Itasca Horizon 36GD with the C-7 330HP CAT, also has fairly dim headlights. And I keep those lenses buffed to the ultra clear status.
