We recommend you use the equipment section on Roll20 only for things you are carrying while adventuring. You should create “divider” items for your belt, backpack, and “free” slots to show what items are where, as well as how many slots total each container has. Finally, set the weight of each item to the number of slots it takes up in that container. For your full inventory, including items you have back in storage at the Outpost, using Dicecloud is probably your best bet for managing this, since it has slightly better support for our inventory system and since both you and the DM team have access to this sheet at all times. (Though you can and should track your full inventory on your Gsheet if you’re using that instead.)
