All of the above.and two batteries. But truck sleeps outside.
It will start at -30 not plugged in.
But if block heater is plugged in then remote starter fires it up first try.
I had a block heater on my first 68 Barracuda and it was nice... I would fire up the car in the morning and by the time I brushed off all the snow, I already had heat coming out of the vents... :popcorn:
But don't leave them plugged in all night - killed my electric bill... :mad: :mob:
Put them on a timer to turn on about 1 - 2 hours before you need to leave... :steering:
