It wasn't even that so much. You simply gank every single thing in the dungeon and then strip mine it at your leisure.
People talk about avoiding combats but, I never quite understood that. You meet 10 orcs. IIRC, that's 150 xp total for kills. Piddling. But, it's not. The orcs all have swords - 7 gp each (1/2 value), and chainmail at 22 gp each. Now, we're looking at 440 xp for a very easy encounter. You can generally gank 10 orcs in a single round if you play your cards right.
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?
Good luck with that in, say, Temple of Elemental Evil. Or did you have a DM that would actually allow you a small army of hirelings that would would be willing to even go on a protracted delve and magically disappear when combat started so they'd be safely out of harms way? Or did you not bother with encumbrance and somehow have all those mundane sellables not count until they were conveniently being carried by your small army of henchmen? Henchmen who would never think of turning on the guys who hired them for a lifetime of riches?
Who doesn't bring a wagon? Have you ever tried taking a wagon through the bush, much less a jungle with no roads? Or a volcano lair? Or into a desert? Did your DM skip the rules for trying to get a beast of burden into an actual dungeon? Where are these dungeons you've been crawling - 2 blocks down from the tavern? Maybe conveniently located next door to Smilin' Sam's Second Hand shop?
I never said anything about tracking minutia. I said some groups skip the post crawl loot recovery, and I said that there's fun to be had in those sorts of operations.
