Howdy Y'all...

Does anyone, that uses AutoTurn, have an expanded vehicle library? Or knows where to find one? I'm looking for a variety of vehicles, specifically Fire Engines. I know that emergency vehicles change per local needs and can vary per manufacturer. If I know the vehicle specs, I can build it in AutoTurn. I'm looking for a large Fire Truck with the following turning radii:

45-foot centerline radius
35-foot inside radius
55-foot outside radius

Thanks in Advance...
