Here is what I'm working with 1999 E250 built by Leader Emergency Vehicles
Overhead console with Emergency start,Fast idle.
Front storage cabinet.
Rear TV,VCR
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.
