At our company we employ the use of a 4x4 Gator type vehicle either having 4 or 6 wheels. The rear dump bed is modified to hold a folding stretcher and the remaining room has one rear facing seat and plenty of room for gear. Will hold two in the front seat onrear facing medic and a patient easily. I have treated a cardiac patient in this unit on the room and it is stable enough for work at low speed. Wheel base is half that of a truck and runs on a gasoline engine. This vehicle is trailer portable so it parks inside of our command unit for events and it also goes through crowds easily. We tried the electric and gas Golf carts but this is the best option.
