We had lived in one home for 38 years. We brought down exactly what we wanted and it fit perfectly into an 8 foot little enclosed trailer. What did we bring? Our kitchen stuff (we cook) and our art. We still have about 3 boxes of "stuff" that got put in that we now agree shouldn't have been brought, but we think we did very well.
It's very very nice to start over, unencumbered, know exactly what you have and where it is, and we recommend it highly!
We miss the VW convertible, but don't miss the care and feeding it needed.
