THIS IS A RARE ONE!
These Orion Vs were originally powered by a DD50 EGR like the 2003 New Flyer buses. However, the CNG enclosure is from ElDorado National CNG buses. AND, it uses a John Deere 6081H. These also have only one door as a suburban configuration.
This should be a variant on the Orion V bus for OMSI 2!
