a management server system enabled for communication over a management network, including management server;

a first material handling vehicle with a first telematics controller and a processor device;

a second material handling vehicle with a second telematics controller, and a second-vehicle vehicle identification;

the processor device of the first material handling vehicle being configured to;

determine that the second material handling vehicle is in proximity to the first material handling vehicle;

obtain the second-vehicle vehicle identification from the second material handling vehicle;

based upon the second-vehicle vehicle identification, determine whether the second material handling vehicle is a missing vehicle; and

log multiple material handling vehicles of the fleet that have been determined to be in proximity to the first material handling vehicle; and

report the log to the management server via at least one of;

a mesh network that includes the first material handling vehicle; and

a direct communications link between the first material handling vehicle and a mobile device; and

wherein the first telematics controller is a multi-channel controller configured to communicate with the second telematics controller over a first channel and to communicate with the management server over a second channel.

2. The management system of claim 1, wherein the first material handling vehicle is configured to form part of the mesh network with a plurality of other material handling vehicles;

and

wherein the processor device is further configured to communicate with at least one of the management server system and the second material handling vehicle via the mesh network.

3. The management system of claim 2, wherein the first material handling vehicle is configured to transmit communication between the management server system and one or more of the plurality of other material handling vehicles via the mesh network.

4. The management system of claim 1, wherein the processor device is further configured to:

download an update from the management server system;

establish a communications link with the second material handling vehicle; and

upload the update to the second material handling vehicle.

5. The management system of claim 4, wherein the processor device is configured to upload the update based upon determining that the second material handling vehicle is a missing vehicle.

6. The management system of claim 1, wherein the first material handling vehicle includes a long-range communication device and a short-range communication device;

and

wherein the processor device is further configured to communicate with the management server system via the long-range communication device and to communicate with the second material handling vehicle.

7. The management system of claim 1, wherein the processor device is further configured to:

report the log to the management server system to determine whether any vehicle within the multiple material handling vehicles is a missing vehicle.

8. The management system of claim 7, further comprising:

a mobile device configured to obtain a first-vehicle vehicle identification from the first material handling vehicle and, based upon the first-vehicle vehicle identification, to establish a communications link with the first material handling vehicle;

wherein the processor device is configured to report the log to the management server system via the communications link.

9. The management system of claim 1, wherein determining that the second material handling vehicle is in proximity to the first material handling vehicle is based upon an availability of a direct communications link between the second material handling vehicle and the first material handling vehicle.

10. The management system of claim 1, wherein the processor device of the first material handling vehicle is further configured to, based upon determining that the second material handling vehicle is a missing vehicle, execute control over a function of the second material handling vehicle, including at least one of:

stopping operation of one or more systems of the second material handling vehicle; and

preventing an operator from executing one or more operations on the second material handling vehicle.

18. The management system of claim 10, wherein control is executed over the function of the second material handling vehicle further based upon determining that an update is available for a firmware or software aspect of the second material handling vehicle.

19. The management system of claim 10, wherein controlling the function of the second material handling vehicle further includes at least one of:

executing a diagnostic function for the second material handling vehicle; and

cycling one or more systems of the second material handling vehicle.

11. A fleet of material handling vehicles configured to be managed via a management network with a management server, the fleet of material handling vehicles comprising:

a first material handling vehicle with a first telematics controller, a first-vehicle vehicle identification, and a processor device;

a second material handling vehicle with a second telematics controller, and a second-vehicle vehicle identification;

a plurality of additional material handling vehicles configured to form a mesh network with the first and second material handling vehicles to facilitate remote communication between the first and second material handling vehicles and the management server;

the processor device being configured to;

determine that the second material handling vehicle is in proximity to the first material handling vehicle;

obtain the second-vehicle vehicle identification from the second material handling vehicle;

based upon the second-vehicle vehicle identification;

determine whether the second material handling vehicle is a missing vehicle; and

establish a communications link with the second material handling vehicle;

log a plurality of encounters with a plurality of other material handling vehicles of the fleet and

report the log to the management server via at least one of;

the mesh network that includes the first material handling vehicle; and

a direct communications link between the first material handling vehicle and a mobile device.

12. The fleet of material handling vehicles of claim 11, wherein the first material handling vehicle is configured to communicate via the mesh network to upload a firmware update to the second material handling vehicle, based upon determining that the second material handling vehicle is a missing vehicle.

13. The fleet of material handling vehicles of claim 12, wherein the first material handling vehicle is further configured to communicate via the mesh network to one or more of:

determine whether the second material handling vehicle is a missing vehicle; and

download the firmware update from the management server.

14. The fleet of material handling vehicles of claim 11, wherein the first telematics controller is configured to operate as a web server to serve a web page;

and

wherein the web page enables control over the first material handling vehicle for a mobile device accessing the web page;

wherein the first telematics controller is a multi-channel controller configured to communicate with the second telematics controller over a first channel and to communicate with the management server over a second channel.

15. The fleet of claim 12, wherein the processor device is configured to, based upon determining that the second material handling vehicle is a missing vehicle:

determine a status of firmware installed on the second material handling vehicle; and

based upon the status, upload the firmware update to the second material handling vehicle via the communications link.

17. The method of claim 12, further comprising:

implementing a remedial measure for the second material handling vehicle using the first material handling vehicle, based upon determining that the second material handling vehicle is a missing vehicle;

wherein the remedial measure includes one or more of;

stopping operation of one or more systems of the second material handling vehicle;

preventing an operator from executing one or more operations on the second material handling vehicle; and
