Really? I'd plug that thing in as soon as I parked it! That's on somebody else's bill.BIGBADDODGE said:I have been in the U.P. here in MICH. when it was -12 air temp and I went to a holtel not knowing that they had pole all over that you could plug in, so I didn't bring a cord (dumb-a!!) well it started fine after a few min. waiting on the block heater to warm up but man did it rattle.
