Neal, when you do pull into a truck stop and go to park it, roll forward and back for about 10 minutes or so. (It will cool off your tires and you wont make ice under the tires for when you decide to pull out.) It cost me $50.oo to learn that lesson.
DO NOT put your trailer parking (maxi brakes) on, just use the tractor brakes for parking.
A little alcohol (Safety brake) in your red air line will help with frozen air lines and drain the air tanks EVERY day.
NEVER, EVER drive according to the other guys abilities. If you don't feel comfortable driving 60mph in the snow, then don't. Drive at the speeds YOU feel comfortable at.
I got my butt chewed off coming North through Ohio one February by a big time trucker (Billy Big Rig) because I was running at 40mph in a 60 zone pushing snow with my front bumper. 10 miles up the road Billy Big Rig trucker that did all the barking was turned around facing South in the comedian. I mosied on by at 40 mph and got where I was going without the aid of a tow truck. Feb. 1974 I-75 was closed right after I got past Lima, OH.
If you hear on the radio (CB or broadcast) that the road is closed in front of you, then find a safe haven, preferably a truck stop.
Never let your fuel tanks go below half in the winter up in the frozen north.
Even IF the price of fuel is higher in the north, most of the northern fuel is already 'winter' fuel. (Brand names) Summer fuel from down South will gell up sooner than northern winter fuel.
