Hey, I've said it many times before. If it doesn't have a good purpose, why even have it in the game. If you can easily send and retrieve everything to and from camp, then encumbrance has no real purpose at all.
But if you flip the script, what's the point of making players slowly walk back to camp, dump everything, and jog back? If you don't have random encounters or anything to make travel back and forth a potential risk, then all you're doing is creating an annoyance for players.
