Run the truck all night in negative temps or plug it in?

On third thought, I’d leave it running. Lol. Keep the trailer brakes released. Instead of losing air, and having to deal with all that crap.

 

Wind chill has nothing to do with air temp. I've never got how people always bring up wind chill. Driving your truck down the road when its below 0 is the same result. The wind just drops the temperature to air temperature faster than no wind.

 

Release the trailer brakes and hit the brake drum with a hammer,they'll release.Flat spot the tires with too much dragging.
Idle overnight 900 or more.See if it can hold a good temperature at 900 rpm.If it's really cold bump it up to 1100 or 1200.

 

Sounds like some real ####ty equipment.

 

I would leave it running and before setting the brakes I’d take a spray bottle and put pre mixed coolant in it. I’d spray my truck and trailer brake drums good and then pull back and forth to coat everything.

I recently had a truck sit 36 hrs plugged in with brakes and fuel treated. 8 hrs before it was set to head out I fired it up and let it run from 9pm to 5am so no surprises in the morning. This was -2 to -8 degrees actual and newer 2021 Cummins with fuel tank heaters. It would have been fine but didn’t want to take any chances. An ‘04 like that I’d 110% leave it idling.

I don’t like to take chances over $30 or $40 bucks when the worry, headache, Or a road call is far worse. Not to mention potentially being late.

 

Chock a tire front and back don't set the brakes..
