I do electrical work on brand new fire apparatus. Been so for 4 years now this summer. Pretty neat gig. I've work on trucks that went all over the US and a few different countries. Always something new.
Here is one of our newest trucks in action:

Coolest part is, I was able to take a ride in one of our trucks from New Jersey to deliver it to fleet in Queens and then bring back another new truck of ours for a little touch up. Best work trip ever.
