Using a battery to power an inverter for a resistive heater is VERY inefficient - you'd get as much heat from the inverter as you did from the block heater (which means you'd waste half the battery charge).
Keep the truck running well, and just use the battery (batteries) for cranking (including the built-in glow plugs). If you absolutely have to use the block heater, buy a generator rated for more than 1200W @ 110VAC.
