My step deck trailer doesn't couple far enough forward to cover my front axle tires. This has led to water and mud being kicked up against the back of my cab. I finally did something about this and purchased an aftermarket Minimizer set of fenders that were longer and specifically made for the wide base singles that I use. Below is a picture of the stock fenders, which shows the gap where water and road debris gets kicked up against the back of the truck.
The stock fenders work on most trailers. However, step deck and other specialty trailers sometimes set further back from the kingpin. Below are pictures of the new Minimzer fenders installed on my truck.
