when i get home from school every day i plug my truck in for about 35 minutes but when i go to start it the wait to start light still comes on for about 30 seconds. sound right. i can leave it plugged in in the morning because u leave at 630 and dont get home til 245 and i dont think it needs to be plugged in that long.

 

Up here in the -30 temps I have the guys use an outdoor rated plug in timer, 3 hrs does the trick when it's -30..

 

It takes longer than 35 min to heat up all that cast iron .

 

Get a timer. ~$35.00 at home depot. 2-3- hours should do it.

 

Yep. Mine runs about 4 hours a night. Timer was $10 at the Home Despot.
