Is anyone in the northern states using a grill cover in the winter? I am awaiting delivery and if I needed one I would rather go ahead and order it to have it here in advance. I also have a 3.0 Jeep GC with the ecodiesel, and was curious if you guys thought I would need one for it as well. I do a mix of mostly around town driving with occasional highway trips of 2+ hours each way 1-2x a month.
