The flaps are Weathertechs. I have them only because in the salt belt holes cause rust. If I was buying again, I'd rivet on a long bit of longer mud flap cut from a fleet store mud flap on the fronts because, as you can see in the photo, I live on a long dirt road. Rear flaps are fine.

The truck has the tow package, but not the HD package.

I agree the tires aren't that good in mud, but I like the quiet and predictable good grip in snow and ice. Besides, mud is the tractor's problem.
