As expected, (lol), I'll start with a few suggestions..
Lock de-icer...it's always a good idea to carry a pocket sized hand sanitizer with you, but the alcohol in it acts as a lock deicer as well when sprayed liberally on a key and inserted in the lock a few times....
Windshield de-icer in a spray bottle works wonders, especially to thaw windshield washer squirters, locks, etc..
Stuck on ice? Carry a small bottle of bleach..pour a little on top of the drives, and after a few minutes it will gently soften the rubber enough so you can drive right off the ice..
If you are pulling a trailer, never set the trailer brakes when parked for a extended period of time, as the shoes will freeze to the drums..and you may end up dragging the trailer tandems...there is no power (like the tractor drives) to break them free..
There used to be a product called " slushbusters" that stuck to the windshield wipers lower path that was like a speedbump to knock of the slush buildup on the wiper blades. Trico wipers also make a winter wiper blade that has a rubber sheath on the wiper to prevent snow and slush from clogging them up. I swear by these.
A 5# bag of icemelt is a good item to carry too.
How many times have you went to a fuel stop only to find the squeegees are frozen solid in the reservoirs? Go to harbor freight and get a squeegee that has a sponge thing on it, and an extendable handle on it. Carry a squirt bottle with below zero windshield wash solution in it...that you can spray the foam part of the squeegee with...and spray off the lights reflectors, and reflective tape with and wipe with a rag..
I hope this helps someone...
