Chevrolet offers a chassis for nearly all types of ambulances. The most popular Chevrolet chassis is the G4500 which are used for Type III ambulances and can support the same modular box size as a long wheel base type I, optimizing your ambulance needs and your budget. The G3500 can be used for a type II van or a smaller type III ambulance. Lastly the Chevy Silverado C3500 short wheel base type I ambulance is a more affordable type I option.
