So, you kill the orcs, and pile the bodies up in the corner. Wash, rinse, repeat with every single encounter in the dungeon, continuing to add to the pile of corpses. Drop a Detect Magic on the whole mess to pick out the good stuff and you have now strip mined a dungeon.
Since everything's dead, you can take a fair bit of time getting everything back to town. And, half a dozen hirelings can carry a whole pile of loot. Never mind horses, donkeys and the like. You can likely get the whole lot in a single trip. "Jury rigging litters"? Dude, amateur. Who doesn't bring a wagon?
Tracking minutia? Dude, we tracked it down the COPPER piece. When we cleared a dungeon, that sucker was BARE.
I find it hilarious that people talk about smart play being the rule of the day, but, apparently, the goal of smart play isn't to maximize profits and minimize risk. Whodathunk?
My AD&D players did that sort of thing all the time.
