Trailer brake upgrade question

Drum has a lot of advantages over disk. Two of the biggest is they can apply more braking force and they last longer.

Uh, what? They definitely don't provide more stopping power. That's why cars went from all drum, to front disc back drum (most of the stopping is done by the front), to all disc. They last about the same, but pads are much easier to replace than shoes and they seat faster. The only advantage of drums is they're much cheaper and (usually) don't get wet when traveling.
