Ok, you can fit 62 wood in the virtual inventory that sells for $2,604 alone, then you can load 3 stacks of wood in the trunk by maneuvering it so that the trunk is close to the wood and scrolling to the first option which is "scoop wood". Wood is in stacks of 20 so that is 60 more timber, this sells for another $2,520. Then there is the 23 extra you can carry in your inventory which sells for $966. All of this is $6,090 in total.
