When I first moved down I brought down loads of stuff in totes and luggage. On the declaration form I just put in my information and left the declaration section blank. When I went to the declare line I told that I was moving down and let them go through everything and had them fill out the declaration section and ended up paying $100 in duties. Maybe it was just a good day. I didn't try to hide anything just let them know it was all personal belongings and let them decide what should be declared. Being very pleasant, helpful and subservient to the officer probably helps as well. Argue or lose your cool and you're done.
