The 7.3's had a factory option call charge protector or battery saver I forget exactly what it was called. Anyway you could set the idle up to 1300 RPM's.

Mine also on a cool day went to 1000 RPM's on a cool day and as soon as you touched the brake it goes back to normal. The glow plugs stay on in the 7.3 for two minutes. Plugging it in on a cold day gives me instant heat which is very nice especially if there is frost on the windshield
