If you’ve looked on Amazon for hitch mud flaps, the price tag probably caused you to google for a DIY solution. Well it’s easy and it will cost you under $30 depending what tools you have.
Items needed: 2” square tubing. 1” to 2” angle for holding the flaps. Misc bolts/nuts. Welder to make things super easy. Mud flaps. I bought mine at lowes in the tile section. I found vinyl 20×20 mats that are just as flexible as rubber mud flaps.
Measure, cut, weld, paint. Do I really need to spell things out?
