If you havent figered it out yet. Put the stuff back into your truck. Go to the shed and click the button "store From Truck" and then don't click anything else. Exit out. If you listened when you clicked store from truck the first time, you'd have heard the task complete sound. Then you can access the contents to put them in your house. Clicking on the content will out it out of the warehouse which is used to check things you havented varafied yet. Or if you want to fix/repair an item.
