[Angel And The Wolf]

I wonder how hard it would be to attach a diesel powered pusher trailer for highway trips? EV around town, without the weight of the ICE and, with the trailer attached, long range diesel for extended trips. I know I could haul a generator to feed the EV battery, but with the extra step of mechanical to electricity, there is an extra loss of efficiency. Better to drive an axle directly from the engine. The trailer hookup could be rigid, side to side, with hydraulic cylinders on each side to tilt the trailer for turns.
