I like the thinking! On my last tow rig I had the rockers done from the front wheel wells all the way to the rear bumper and I plan on doing it again on this rig as well. The tires tend to send rocks and other debreis up and chip the paint. Even with the big mud flaps that I have it still tends to chip away at the paint on the training wheel covers. Great idea to also line X the top of the fender flares.
