How many of us are there? Owners of Dodge based RV's?

Leeann and Eric:

Two entirely different countries, plus Eric's fixture is singular and Leeann's converter is plural. Finally, there are loopholes in the laws for trademark and brand registration that 'allow' that kind of thing. In the U.S., registration at the state level permits the same name being registered by an entity in a neighboring state. Likewise, at the U.S. federal level does not preclude the same name being used in another country.
