Keeping yourself warm overnight when idling is not an option.

A diesel fired heater like this:

There are sleeping bags that will keep you warm to -40, just be prepared to wake up to a cab full of frost. I have German Army sleeping bag for decades exactly for this purpose. Don't depend on your engine or any other fuel source to keep you warm in event of break down, doo doo happens.

 

I have a sleeping bag good for -40
I have a heater but have only used it 3 nights this winter. Spend most of my time in upper Midwest.

 

Idle, cab heater like esper or webasto or hotel.
My health and a restful sleep is too important for anything else.

 

Why can't you idle?

 

If you own the truck install bunk and engine heaters. If it’s a company truck they better have something for heat or I idle . I refuse to work for companies that base bonuses on idle time unless they have a working APu

 

There are diesel fired bunk heaters on Amazon for under $150, installed one in January and the driver loves it. Even if you have to replace it every year it's way cheaper than a Webasto or Espar.

 

Well, until it burns down the truck....

 

Thats why if you look at the bottom of the add on Amazon.. it shows a smoke detector & a 5.lb fire extinguster.. and says.. you also might like these ...
