Parking Antique Ramp Truck on Residential Property

The 2 previous post are the points I want to use for fighting back. I want to point out to the guys my truck was tow-truck, but it is antique vehicle now.

Antique vehicle by DMV definition cannot be tow-truck because when applying for antique, I did sign a agreement with DMV that I cannot use this truck for daily driver, towing, go to grocery store etc; that antique license should overdrive the truck towing ability.

Any code enforcement member here? Is my point valid?
