Ford F-150 Electric Pickup May Get Newly Patented Range Extender in Its Bed
It looks deceptively like a toolbox, but it could be used to increase the range of the upcoming electric F-150 pickup truck.

Unfortunately, that isn't gonna work. A gas powered generator would need as much engine size and fuel tank size as an automobile has now (Plus a large generator) to be able to provide enough power to extend the range to what an automobile gets now. It actually would take quite a bit more than that, considering the extra tire rolling resistance and air resistance and weight of the trailer. There ain't no free lunch.
