Enjoy a great night's sleep anywhere you stop. 12 volt bunk warming pad goes "on the mattress" under you (heat rises). Plugs into the lighter socket. Pre-warms bunk and gets rid of dampness. Heat soothes and relaxes tired back and legs. Helps lull you to sleep. Keeps you warm all night without idling the engine. No more engine noise, vibration, or exhaust fumes.
Automatic Comfort Control thermostat regulates heat based upon the setting you select (1 - 7). It adjusts the heat in the bunk for any change in cab temperature. As the cab cools, it supplies just the right amount of extra heat to keep you comfortable. Highly Efficient - the "on the mattress" system with automatic Comfort Control converts 98% of the battery power consumed to heat. Average current usage is about 3 amps. Similar to leaving a few clearance lights on. ElectroWarmth® Bunk Warmers do not cause battery or starting problems.
