I would think you could do something electrical fairly easily. Perhaps modify an add-on rear window defroster kit to fit under your plastic/rubber pads? If you're really slick, you could scavenge a small loop off your radiator and pipe hot coolant through both tubes before returning to the engine cooling loop!Anyone know if they even make them? I thought about it when I slipped trying to get up into my truck today and there was ice on them..good thing the grab handle didn't bust.. thinking of what i could use to rig something up..
