Just to clear up a point, and not to be picky, but your truck is actually not affected by wind chill. So, if it is going to be 25 degrees out but high winds will make the wind chill go sub zero, don't be to concerned for your truck. It will be affected only by the 25 degree temperature, so you only have to prepare your truck to that temperature, as far as you normally do.
What you have to do for yourself, and your animals is a different story. Those things are certainly affected.
By the way, I had to have the service department add power steering fluid to my Volvo Tractor (service controls the lease, and the fluids). I could swear he put in ATF (Auto-matic transmission fluid). It was the same red color and poured the same. I meant to ask the mechanic but got distracted for a moment and ultimately... forgot! I wonder if it was ATF or a Synthetic PS fluid. I'll find out.
