An integral tank frame for an emergency response vehicle is provided. The integral tank frame includes a tank mounted within an envelope of space of a ladder frame. The ladder frame has side rails that support the tank on either side thereof. The tank can be mounted to the side rails such that it extends across the top of the side rails, interior to the side rails, or a combination thereof.

1. A frame for an emergency vehicle, comprising: a pair of longitudinally extending side rails;a plurality of lateral supports extending transversely between the pair of longitudinally extending side rails to form a ladder shaped configuration, wherein an envelope of space is defined between the of longitudinally extending side rails and between an adjacent pair of the plurality of lateral supports;a tank mounted within the envelope of space, the tank configured to carry a flame retardant fluid; andwherein the tank includes integral side rail portions, the integral side rail portions positioned on opposing sides of the tank and configured for mechanical attachment to the pair of longitudinally extending side rails. 2. The frame of claim 1, wherein the tank is mounted directly to the pair of longitudinally extending side rails, and forms a load bearing portion of the frame. 3. The frame of claim 1, wherein the integral side rail portions form load bearing members of the frame. 4. The frame of claim 1, further comprising a flame retardant fluid carried within the tank. 5. The frame of claim 4, wherein the flame retardant fluid is one of water or foam. 6. The frame of claim 1, wherein the tank includes a port configured for connection with a secondary tank. 7. The frame of claim 1, wherein the tank has a fluid capacity of about 100 gallons to about 2000 gallons. 8. A frame for an emergency vehicle, comprising: a pair of longitudinally extending side rails;a plurality of lateral supports extending transversely between the pair of longitudinally extending side rails to form a ladder shaped configuration, wherein an envelope of space is defined between the pair of longitudinally extending side rails and between an adjacent pair of the plurality of lateral supports;a tank mounted within the envelope of space, the tank configured carry a flame retardant fluid; andwherein the tank includes integral side rail portions, the integral side rail portions extending through the tank such that the tank surrounds the integral side rail portions, the integral side rail portions configured for mechanical attachment to the pair of longitudinally extending side rails. 9. The frame of claim 8, wherein the integral side rail portions form load bearing members of the frame. 10. A frame for an emergency vehicle, comprising: a pair of longitudinally extending side rails;a plurality of lateral supports extending transversely between the pair of longitudinally extending side rails to form a ladder shaped configuration;a tank configured to carry a flame retardant fluid mounted directly to and extending between the pair of longitudinally extending side rails, the tank including a port for fluid communication with an interior of the tank;a pumping system mounted to the pair of longitudinally extending side rails and connected to the port of the tank for pumping flame retardant fluid into and out of the tank; andwherein the tank has a T-shaped cross section, with a first portion having a first width less than a second width of a second portion. 11. The frame of claim 10, wherein the pumping system includes a motor in fluid communication with the port of the tank for providing a pumping force to pump the flame retardant fluid into and out of the tank, the motor interposed between the pair of longitudinally extending side rails. 12. The frame of claim 11, wherein the pumping system includes a pump housing in fluid communication with the motor and with the port of the tank, the pump housing configured to divert fluid pumped from the tank to a conduit connected to the pump housing, and configured to divert fluid into the tank. 13. The frame of claim 12, wherein the pumping system includes a plurality of ports for selectively diverting fluid from the tank, and wherein at least one port is configured for connection with a secondary tank. 14. The frame of claim 10, wherein the second portion is mounted on top of a top surface of the pair of longitudinally extending side rails. 15. The frame of claim 10, wherein each one of the pair of longitudinally extending side rails has a C-shaped profile that defines an interior channel, wherein the second portion of the tank extends into the interior channel of each of the longitudinally extending side rails. 16. A frame for an emergency vehicle, comprising: a pair of longitudinally extending side rails;a plurality of lateral supports extending transversely between the pair of longitudinally extending side rails to form a ladder shaped configuration;a tank configured to carry a flame retardant fluid mounted directly to and extending between the pair of longitudinally extending side rails, the tank including a port for fluid communication with an interior of the tank;a pumping system mounted to the pair of longitudinally extending side rails and connected to the port of the tank for pumping flame retardant fluid into and out of the tank; andwherein each of the pair of longitudinally extending side rails includes a top surface, the top surface of one of the pair of longitudinally extending side rails coplanar with the top surface of the other one of the pair of longitudinally extending side rails, and wherein each of the pair of longitudinally extending side rails includes a bottom surface, the bottom surface of one of the pair of longitudinally extending side rails coplanar with the bottom surface of the other one of the pair of longitudinally extending side rails, and wherein the tank is mounted to the pair of longitudinally extending side rails such that it does not extend above the top surfaces of the pair of longitudinally extending side rails, and such that it does not extend below the bottom surfaces of the pair of longitudinally extending side rails.
