I was just wondering if anyone else leaves thier winter front on. The day i got my truck Nov. 11th i put it on and have had it on sinse then. I plow and hit the speed limiter ):h when weightless in the front. Some on here have noted that the winterfront is a bad thing, restricting air flow and building up temperatures. The way i use my vehicle should i keep it off? What about on my trips to Canada in below freezing weather towing my 10,000+ snowmobile trailer? If i should keep it off is that in regards to the grill cover, the bumper cover, or both? Im guessing the bumper one blocks in the intercooler and the grill one blocks the radiator?
