Try two batteries in the cab that will charge off your alternator, hooked to an inverter and start the heater one hour before you plan to get back in.
It might take the chill off the block allowing it to warm faster.
Or you could carry a 500 watt solar array to charge the batteries as they drain and warm the block.
