I keep it in the garage temp set at 40

 

Thats what Im looking into, too bad its a grand.

A cheaper option that im going to do for now is to get a little 12v electric heater that plugs into the cigerette lighter. Truck shops online have all sorts of junk that runs off 12v. And they have heated seat covers that plug in too.

Plugging your truck in over night is a must in cold weather. My heater comes to life after a couple miles tops when its in the 20's-30's

The reason why diesel take longer to warm up is because the blocks are soo much thicker. When we bench test big rigs after we rebuild the motors we can run them for 20 minutes with no load, on very high idle with no coolant and have no issues of overheating. Granted those blocks are a lot bigger.
