So where with your rim brakes you would adjust the pull of the cable and also the position of each pad, with disc brakes (BB7) the equivalent to the pad adjustment is done with the two dials, not hard at all. replacing them is pretty easy as well. watch a video on you tube and you'll feel a lot more confident. And just like you can put kool stop pads on your rim brakes, they also make pads for mechanical discs. So when the originals wear out you can switch over if you want. As long as you get discs with both inner and outer adjustment dials, I just don't see any problem. as for pulling a trailer, I haul `60lbs on a burley travoy attached to my recumbent trike (which has the crappy bb5 discs) and I have to say coming down a hill with a load is definitely better with the discs. I used to pull that load with my BF pakIT with caliper brakes and they are shimano 105's which are pretty good, but the discs are better.
