I actually feel quite guilty about not having mudflaps on my 1965 Land Rover.
When I bought the car, it only had one mudflap on, so my son bought me a set of new mudflaps for my birthday. I put them on and drove for a while before I noticed that one of them was starting to come off. I didn’t know why, but it had started to rip where the fasteners bolted to the bracket. I tried to re-attach it as best I could.
Then, during a trip up into the mountains, I discovered the problem. At one point, we had to turn around on a narrow trail so I backed the Land Rover a little ways up the hill at the side of the trail. We pulled forward again leaving a mudflap behind. As I had backed up, the mudflap tore off when it got caught between the wheel and the hill.
I know that a responsible vehicle owner would have mudflaps, but I can’t really afford to replace them every time that they get torn off so I now drive it mudflap-free.
