I'm leaving on a two week road trip later today and just thought I ask. I currently have only the rear flaps on the truck as the front ones rub somewhat because of my 4.5bs wheels. I do have fronts, but so far the plan is to put them back on the truck for winter when I put on stock wheels and winter tires.
I'll be going through Montana, Idaho, Wyoming, Oregon, Washington in the next few weeks. Do I need to put front flaps on? Is it illegal to not have front flaps? Thanks.
