The vehicle frame assembly of claim 1, wherein the second portion comprises a tubular extrusion mounted to the first portion. 3. The vehicle frame assembly of claim 1, wherein the first and second portions are integral as a single unitary body. 4. The vehicle frame assembly of claim 3, wherein the first and second portions are an extrusion. 5. The vehicle frame assembly of claim 1, wherein the at least one of the first and second chassis rails further comprises a plurality of access ports configured to provide access to the fluid cooling passageway. 6. The vehicle frame assembly of claim 1, wherein the second portion defines a first enclosed fluid cooling passageway extending along the first portion and within the internal cavity, and further comprising a third portion defining a second enclosed fluid cooling passageway extending along the first portion and within the internal cavity. 7. The vehicle frame assembly of claim 1, wherein each of the first and second chassis rails has a first portion defining an internal cavity and at least a second portion defining an enclosed fluid cooling passageway extending along the first portion and within the internal cavity. 8. The vehicle frame assembly of claim 7, wherein the first chassis rail is configured to facilitate transfer and cooling of a fluid from the second component through the fluid cooling passageway to the first component and the second chassis rail is configured to facilitate transfer and cooling of the fluid from the first component through the fluid cooling passageway to the second component. 9. The vehicle frame assembly of claim 8, wherein the first device component is a radiator, and the fluid is a coolant. 10. The vehicle frame assembly of claim 8, wherein the second component is one of an axle, a motor, and a motor controller. 11. A vehicle comprising: at least one driven axle assembly; a motor coupled to the axle for driving the axle; and at least one frame member formed from a heat-conductive material and supported relative to the axle, the frame member having an enclosed internal fluid cooling passageway extending along the frame member; wherein the frame member is in fluid communication with a vehicle component and with a fluid source supported relative to the frame member in order to facilitate the transfer of a fluid within the fluid cooling passageway between the fluid source and the vehicle component and cooling of the fluid by contact with the heat-conductive material of the at least one frame member. 12. The vehicle of claim 11, wherein the frame member is a first chassis rail, and further comprising a second chassis rail supported relative to the axle and generally parallel with the first chassis rail, the second chassis rail having an enclosed internal fluid cooling passageway extending along the second chassis rail. 13. The vehicle of claim 12, wherein the first chassis rail is configured to facilitate transfer and cooling of the fluid from the vehicle component to the fluid source and the second chassis rail is configured to facilitate transfer and cooling of the fluid from the fluid source to the vehicle component. 14. The vehicle of claim 11, wherein the fluid source is a radiator and the fluid is a coolant. 15. The vehicle of claim 11, wherein the at least one frame member comprises at least a first portion defining an internal cavity and a second portion defining the enclosed fluid cooling passageway, and wherein the second portion extends along the frame member and within the internal cavity. 16. The vehicle of claim 15, wherein the second portion comprises a tubular extrusion mounted to the first portion. 17. The vehicle of claim 15, wherein the first and second portions are integral as a single unitary body. 18. The vehicle of claim 17, wherein the first and second portions are extruded. 19. The vehicle of claim 11, wherein the at least one frame member further comprises a plurality of access ports configured to provide access to the fluid cooling passageway. 20. The vehicle of claim 11, wherein the vehicle is an electric traction vehicle and the motor is an electric motor. 21. The vehicle of claim 11, wherein the vehicle component is at least one of the driven axle assembly, the motor, and a controller coupled to the motor. 22. A method of producing a vehicle frame for cooling a fluid, comprising: providing first and second generally parallel chassis rails formed from a heat conductive material, wherein providing each of the first and second chassis rails includes: providing a first portion defining an internal cavity; and providing at least a second portion defining an enclosed fluid cooling passageway having a heat transfer surface area extending along the first portion and within the internal cavity; configuring at least one of the first and second chassis rails to be coupled to at least a first component and a second component; and configuring the first and second chassis rails to provide a routing within the fluid cooling passageway between the first component and the second component, to cool the fluid as it flows between the first component and the second component. 23. The method of claim 22, wherein the providing second portion comprises providing a tubular extrusion mounted to the first portion. 24. The method of claim 22, wherein providing each of the first and second chassis rails further comprises providing the first and second portions such that they are integral as a single unitary body. 25. The method of claim 24, wherein providing the first and second portions such that they are integral as a single unitary body comprises extruding the first and second portions. 26.
