Staying Warm This Winter?

I was just wondering if you "old sages" had any advice for those less experienced in cold weather on how to stay comfy in the cab (the cheaper the better), particularly considering the idle restrictions on most of the company drivers (and the direct cost of fuel on O/O's).

 

I agree totally with a good quality sleeping bag and a couple of good old fashioned heavy blankets (and keep most of your clothes on). My only problem used to be once the temperature reached the low thirties or twenties, the face would get cold and it would be time to fire up the engine for a little while. Never did try any of the small 12V heaters that you could plug in, just didn't feel too comfortable about thier safety.
