Depends what classes you're 3boxing. With something like druid, warrior, priest you could probably manage to 3man most leveling dungeons. If your main is a caster you might have a rough time since the caster will go OOM often as the only DPS and casters just lack DPS in general compared to warriors with cleave and whirlwind. Grinding non elite world mobs won't be very good XP with 3 characters. Questing might be your best bet.

Some classes could probably manage dungeons as a single class team. Shamans, paladins and druids seem like the obvious choices. Anything fairly tanky that can heal would work.

I don't see any advantage to boxing a single class team in vanilla though. You miss out on a bunch of buffs and utility for no real gain. You also end up with one class leveled which limits your raiding options. A balanced group with a healer or two plus some ranged DPS increases your chances of being a viable addition to any 40man.
