As was said in another message: While playing the game and having the Trainer in the Editor menu, select an item such as an apple. While selecting the apple in the character inventory list, Tab to the Trainer Inventory Amount and put a - "minus" in front of the number of the item you selected, preferably an apple. Example: Say you have 3 apples, put a -3000000 in the Trainers Inventory Amount. Your weight will drop a lot. You can carry a ton of logs or items. Very simple to do. Do not do it with other items because you'll most likely need those Items
This also works for the Storage Bins in your buildings as well.
Thank you so much. Your advice is brilliant, and helped me a lot especially in relation to construction. Makes building tasks easier. 🙂
