This light repair unit is a 2001 Ford F450.  It is used for light repairs in the field to keep from bringing apparatus into the shops unecessarly.  Take a look at the tool box near the mechanics knees.  The Crown heritage of LA City Fire has not been forgotten.
This Taylor-Dunn electric cart is used to transport parts around the shop complex.
This Harlan tug is used to move inoperable apparatus on and off the shop floor.
