Using this Dirty Diesel trailer hitch cover is a breeze. First, make sure your trailer has a 2' standard receiver. Then, slide the hitch cover onto the receiver. You'll need a hitch pin to hold it securely in place. As for maintenance, a simple wipe - down with a damp cloth will keep its black and white color looking sharp. Just be careful not to use any abrasive cleaners that could scratch the 3D printed surface. Also, regularly check the hitch pin to ensure it's tight and the cover stays put during your travels.
