This topic has been hotly debated in several threads.

As already pointed out, a generator is not as efficient as a pusher due the mechanical -> electrical -> mechanical conversion. A pusher generates mechanical energy and applies it directly to propelling the vehicle.

The advantages I see of using a generator:

1. Backup home power in the event of outages
2. Generator does not push the vehicle and introduce dangerous driving dynamics
3. Generator can be sized for the average load and run at a constant speed, utilizing battery power for acceleration and hills

Either way, a generator or pusher is impractical since most families have multiple vehicles, one of which could contain an ICE. Furthermore, the cost of a pusher or generator exceeds the cost of a normal used car. There just isn't a point to either a generator or pusher, since better alternatives for distance travel already exist.
