I'm doing the same thing for a local ready-mix company to use in parades. I just got started and have working on getting videos up on it. I'm using a 96 Dodge 3500 with 12 valve Cummins and automatic transmission. The guy I'm building it for wants to include the Dodge the instrument cluster so I'm having to go through the wiring harness to figure out how to make it work. I'll be watching your progress for sure!
