'Pickable' items are 2 weight, with the except of moonshine, meth, rock, and oil (needs special truck to carry).
Once you process the ingredients it turns to 1 weight. With the exception of moonshine, meth, rock, and oil, that are now 2 space once processed.
Water = 1
Tactical Bacon/ Donuts = 1
Redgull / Coffee = 1
Bloodbags = 5
Spike Strips = 15
Epipens = 10
Pickaxe = 2
Lockpicks = 1
For the most part this is what you're going to be using/running. So I hope this helps
