We didn't name things, but our kids did. And I'm glad.
Our truck at the time they were born was named "Chevy" by them. They didn't know it wasn't original, and that's what made it so cute. When they were 9, we sold that truck and they cried all the way home. One of the boys will get teary to this day talking about "Chevy". To our boys, Chevy was a part of the family.
When we bought the current truck, it was light years ahead of "Chevy", but they whined for months about how they could never like it. We decided as a family that in order for it to join the family, it would have to have a name. Their great uncle, Seymour, passed away that year...so we named the new truck "See-more". Get it?
Our trailer is just..."the camper".
