Ok 3,200 plus newbe TD 2500 4x4 crew cab owner. Only had a diesel rabbit back in the 80's only time the block heater wasn't plugged in is when I was driving. Was lucky I could plug in at work. My question is living in SE Michigan temps aren't tobad considering other prts of the country. What temperature should I install the cover to truck for the winter. I will be plugging it in when it gets cold but when Driving the truck are there ay temps that will indicate when I should start opening up the flaps?
