i don`t mean to sound plum ignorant,but,when the engine block heater is plugged in, how many things ,if any, does it operate besides engine block heater? ex.; battery heater/ warmer/ charger? i`m just curious if the truck isn`t used for a couple of weeks and is stored where the temps don`t get much above the nightly lows (low to mid 20`s here now)if the engine block heater also maintains "other" systems?
i have learned mucho stuff about these trucks from this page. the little "tidbits"help the most.
