Anyone found a suitable cover for the capless fuel filler(s)? Ford makes a locking plug for 09-14, but of course diesel is larger and was looking for ideas. I live in a windy dusty desert climate and the fuel door can only do so much. As I type we are gusting to 54mph. I hate to stuff a rag in there, but may have to trying to keep dirt out. I guess I could wander through the wife's kitchen for suitable lids to steal! >
