You must be Canada. The FCA provided grill cover in cold climate is yet to reach the states to my knowledge. But Canada it's said to be provided free of charge upon request.
You're well broken in but I'd be happy with that mileage.
I can't believe they are providing you with a winter front in Missouri. There's no need. And mopar says to absolutely not have it installed at temps above 32F
But the best I know is this, mopar updated the cold weather package. It is now a "package" which includes the block heater cable as well as the winter front. As previously you only got the heater cable installed and were at your own responsibility to get a winter cover though FCA says it is necessary for anyone in winter climate that regularly experiences under 30 degrees and is subject to the freezing problems
