Here’s a few Tips that I found out, which might help...
1 - Donate any provisions; like canned goods, fresh fruit, animal skins, horns, meat, various animal parts & food (in general) to the Camp Butcher.
2 - Donate any cash, jewels, loot items & trinkets to the Contribution box.
3 - Save certain flowers, herbs & plants for the women in the camp. Sooner or later some will ask you to find various ones to make recipes... which increases the core Health, Stamina & Dead Eye meters whenever you eat the Camp Stew, or whenever you hunt / cook your own food outdoors, if you use their recipes.
4 - Save the dry goods, books / letters / reading material that seems insignificant, hard liquor, alcohol, moonshine & tobacco for the fellas in the camp. Sooner or later some will ask you to find random stuff like that for them to make specialized weapons; like fire arrows, explosives, special bullets, Molotov cocktails, or poison arrows... which you can restock @ your ammunition tent. Or they will reward you with information about heists, treasure maps & random side missions.
5 - Go fishing or hunting with the fellas in the camp, when available. They will give you tips about which types of bait & lures are best for different types of fish, teach you stuff about hunting and/or take you to Legendary Animal locations (which might not be readily available on the map). Usually these side missions will unlock something useful.
Hope this helps.
