To start the modifying i added a third axle to the end of the truck.
 It increased the truck's length to 2 feet.
 Next I implemented some of Designer Han's modifications.
 I also modified the crane. I took out the string and made it into a removable winch in the back of the truck.
 Finally I increased the crane's length. 
This was difficult as the stock crane was too weak to take the weight of the extension.
 My final design made the crane 3 feet tall when fully extended and 2 feet long.
 I also added many cosmetic modifications such as opening doors, a covered roof, lights stickers etc.
