Wi trail pass or street legal licensing

[captwheel]

A couple of friends bought new Roxor in Wisconsin. They are trying to get trail pass for them. Wi says they are over there 3000 lb limit & will not issue. There are so many different weights of vehicles I am not sure which weight they use. I know of curb side weight, unladen weight, & GVWR. I have heard of people who have been issued trail passes in Wi. Does anyone know of any Roxors that have had trail passes issued to them?
Another thought for this is to license them for road. Do not know if that can be done in Wi. What are pros & cons of licensing street legal?
Thanks for all help, Phil
