Good Script. It's easy to add your own Ambulance Button for the stretcher. Here's the one for Lone Wolfie Ambulance
ConfigurationMedicMod.Vehicles["models/lonewolfie/ford_f350_ambu.mdl"] = { buttonPos = Vector(-46,-169,50), buttonAngle = Angle(90,-90,0), stretcherPos = Vector(18,-95,62), stretcherAngle = Angle(0,0,0), drawStretcher = false, backPos = Vector(0,-170,50) }
