Dieseldragon North shore of Lake Erie.
Good observation, unless it's moving and working it's not making heat and it's surprising how fast the temp gauge drops at idle.
Drove to my deer stand yesterday morning. I have the cold front on (it's not a bra) and temps came up to normal with an outside temp of 5F. Problem is, I don't have a current bush out in the middle of the field to plug my truck into so it sits all day getting cold. By 5pm all the temps were very close to ambient temp. Got in, started up, gave it a few minutes and drove it out of the field. No big deal.
well I installed my cover today , ( I was in Florida until Dec 2 )
and my el cheapo model that FCA gave me is not long enough to go any where behind the headlight ,
and that part is not thick enough to grab on anything , so the video was probaly done with a cover like mine .
the side flaps hold in there with pressure from lastic bands at the top , and outer lower cushions .
...so they are possibly not all made the same , it is not only the closable holes that differ.
Next year I'll wear my glasses and try again to slide behind the grill , 2018 will be like the last winter .
Any suggestions what should I do with my headlights..dunno why every time it's cold, it takes around 20 seconds before the light turns on.
