Here is what I'm working with 1999 E250 built by Leader Emergency Vehicles
Overhead console with Emergency start,Fast idle.
Front storage cabinet.
The jump seat is original, the storage bins I picked up from the junk yard, their from a freightliner sleeper.
The fold up bed from the Freightliner. I haven't figured out how to mount it yet.
I'm not sure what I want to do with this box yet,maybe make it a sink.
The battery box, holds three batterys.
Someday I'll convert it to 4x4.
