Yeah, that's understandable abou making the vehicles first, I was just curious.
Anyway if you need any pics i have pics of three engines, a truck, and my station (it's a volunteer FD so it may not be what you'd want). You might also want to check out American-Firefighter.com. They have a lot of pics of engines, firefighters, etc. They also have forums with literally hundreds of firefighters (including myself) who could answer any questions you might have.
