A guy named sharkey did make a gas pusher to push his EV long distances, used an automatic trans to keep it simple to control from the cockpit (still would beat a generator->charger by a wide margin probably), basically parallel through the road and if his car has regen he can do some emergency charging with it while driving.

I already said the gas generator would be the cheap option, cheap options tend to be inefficient.
A diesel generator putting out 1KwH for 0.2 gallons of fuel could hit 30mpg easy with a regular sized car assuming the car only needs 10kw to maintain 60mph. 0.2gal per KwH is not a high goal for a diesel generator so the vehicle/trailer combo and the driving speed have final say in what the true fuel economy will be.
30 diesel MPGs isn't amazing but it will do the job.
Plus if you only need it once or twice a year who cares what the fuel economy is. Now you could use say between 10 and 50 gallons of gas per years as opposed to 400 gallons (12,000 miles/year with a 30mpg car).
Has anyone even tried pushing a production EV?
