Every truck can be a cold-weather truck. A simple 25 amp wiring arrangement, plugged into a 110 v outlet at the terminal before the truck's daily run, activates a series of immersion heating elements which will raise the engine, radiator, battery, and the fuel in the tanks to summer starting temperatures. The results will be elimination of cold-weather downtime in ambients of as low as −40 F, and assurance of normal battery life, without the addition of any maintenance items such as plumbing or hosing systems.
