The pusher trailer is, by far, the best solution. They are also
relatively cheap to build. Run great with little trouble. No handling
difficulties. Low pollution. You can even run a diesel on biodiesel, if
you can find a clean front clip from a Golf TDI in the bone yard for a
reasonable price.

Most all of the old timers remember Mr. Sharky. A very clever EVer
indeed.
Generator trailers have to be HUGE, expensive, and they often are
very polluting. It takes at least a 10 kW generator to run your EV,
which, don't forget, must also haul the generator trailer. (Yes, 10 kW.
No, a smaller generator won't work at highway speed. Trust me, I've
tried it.) About 1.5 times the juice of the car alone. A trailer adds
an _astounding_ amount of drag. The noise the cheap generators emit
completely ruins the EV experience.
Battery trailers are also huge, and expensive.
