As it was stated above I just make a box outta cardboard first. It doesn't give you an extremely accurate measurment but you can get a good idea of how big the box can be. If you really want to get crazy you can draw out a side view of your trunk on AutoCad or just paper if you don't have that program and try and work it out.
