Hagie's RV, whose graphics were very well received. Designed by Bryan Young. The industrial design team was tasked with generating a design for the service trucks which related to this, but not a blatant copy.
This rendering became my final theme, and the one which was ultimately chosen.
The finalized design for the new service trucks.
The RV is in the background here, and you can see the how the two vehicles are in the same 'family'. One of these trucks' cabs started as white, the other started as red... Believe it or not.
