That's really cool looking, how does it ride and accelerate? One thing that concerns me is all the idle time an ambulance sees, something that is more suited for a diesel engine. A gas engine simply isn't built to do that, well. With Ford and Chevy no longer putting their diesels into the van chassis I am seeing departments come up with some creative solutions, including the Ford V10, or type one ambulances that don't have the best turning radius compared to the van chassis.
The other popular solution is the sprinter van, which as really stupid looking but are holding up well. I'm hoping Ford gets there chit together soon..
