No rotten food, empty bottles or flasks and no bones or skulls.
General rule of thumb: Early game everything except the above mentioned; mid-game only valuable mundane stuff, e.g. hvy or med armour but not daggers or swords (I will grab stackable, almost weightless stuff such as gems); late game only enchanted stuff.
I'm currently in Moonrise ready for round 2 with Ketheric and have about 29k in my pocket. My party of 6 are all equipped with the best gear available. I'm looking forward to getting to Act 3 for a bit of retail therapy.
I watch a lot of LPs on YT and it never ceases to amaze me how many of these Herberts grab absolutely everything but don't know how to sort the inventory. The other amazingly stupid thing they do is to constantly send stuff back to camp (because of weight issues or just to reduce clutter) and then constantly find themselves at a merchant with next to nothing to sell so they are always scratching for cash (cue 20 minutes of agonising on whether to buy the armour piece or the sword). The stuff they send back is usually really light but numerous while they leave armour and suchlike in the inventory while wondering why the weigh hasn't gone down much. They don't understand the barter/trade system either.
