Range anxiety still?
EP Tender range extender trailer (proposed for rental use) for those with extra long EV commutes or taking long vacation holidays. When not towed, could also be a handy home backup generator. The engineer has the backup maneuver figured out...

Why not just get the appropriate Honda or Yamaha generator and put it in the space behind the rear seat?

If they made a pickup there would be no need for a trailer.

The whole thing weighs 440 lbs.
It's supposedly 3500 watt.
A quick Google of 3500 watt gensets shows a rough sizing of 2ft x 2ft x 2ft and 120 lbs.
I'd rather set the genset on a receiver hitch mounted platform and eliminate the extra weight, cost, and complexity of that trailer.
The backing-up solution is clever but I suspect not foolproof. I'm certain the driver can't see it AT ALL (I can't see my Harbor Fright 4x8 trailer); of course a couple safety flags would help (considered putting one or two one that trailer).
It would be entirely too easy to forget it's there and back it into things. Also it was demonstrated on nice level asphalt; I suspect things would not work as planned on worse surfaces.

A 3.5kw generator is not going to produce enough power to push the vehicle down the road at highway speed. It might reduce battery draw by around 30% at speed.
In stop and go, low speed traffic I bet that smaller generator might be able to keep up.

Yes, 3.5 KW is pointless. I would want one nearer to 10 KW, and diesel. Agree with eliminating the trailer and just carrying it from the hitch, although I'm not sure you could find a 10 KW diesel genset light enough.

FWIW: what voltage battery pack? 3.5 kw into a 260v pack for a 170 v maximum dc motor might actually make sense. My SOL1 controller uses the motor inductance to make huge currents on rather low battery current. Ie: motor sees about 1000 amps fron 260 battery amps at 192 battery volts & about 50% duty cycle pwm.
