could you jump start the other car so it will generate its own electric?
could you put the dead battery in your car, jump start your car from your own battery and then fit your battery into the other car?
yes you could supply power to the other battery via you towing electrics but I don't know if it is advisable.
If you have a split charging set up on your towing electrics, your car may not supply electric all the time to the other cr but in truth i'm not sure.
you will need to consider how much current (amps) the car thats being towed will draw so you don't blow fuses in your car.
perhaps picking up the feed for the fridge may allow you to draw sufficient current.
Is there a purpose built cable to do as you want, I doubt it. You may need to make one, not to hard
