Dover was a make of trucks, owned by the Hudson Motor Car Company of Detroit, Michigan.
Dover trucks were based on Hudson's Essex car chassis.
The number of survivor vehicles is very limited; one known restored mail truck was last known to be owned by a private collector in Michigan.
A fully restored U.S. mail truck is on display at Hostetler's Hudson Museum in Shipshewana, Indiana.
[1] Hudson also offered these trucks under the Essex nameplate through 1932, subsequently replacing them with a new Terraplane line.
