Here is the brand new International TerraStar ambulance that the LFD is currently purchasing. This is a large upgrade from the previous Ford F-450 ambulances, the reason behind that is space. The LFD needed more space for medical equipment. These ambulances will be housed in new firehouses due to its size (about 75% of the firehouses are newly built). The Ford F-450 ambulances will still be around, but most of them will be used as spares, sold off, training, and/or used for special events.
The cab is inspired by CC's design. Credit goes to CC.
