Current efforts are underway to allow such normal (Auto, Truck, Farm, RV, etc.) registration, by demanding WisDOT/DMV honor existing state and federal laws. See: http://www.g503.com/forums/viewtopic.php?f=126&t=17919
I expected MVPA would support such efforts, but apparently it's still an undecided matter. I got this recently:
Since I’m working as an appointed member of the MVPA Board of Directors legislative committee, I can help you understand who the people involved are and what their roll is. Remember, the P in MVPA stands for preservation. It is not the Military Vehicle Commercial Owners and dealers association. Believe me when I say there is a great deal of discussion and action at the national MVPA board level about exactly what the roll should be in state legislative issues. It may or may not include advocating for commercial or regular use.
I'm not trying to push MVPA and it's members one way or another. But if MVPA supports both collectors and users of milvehs, we could use their support here. I'm just asking, where does MVPA (and it's members) stand?
