While driving through the middle of nowhere Texas, I noticed several cars slow down while passing our trailer. We stopped at a rest stop along the way I did a walk around… and I found the trailer wheel well covers were both very loose.
Most of the screws that hold the wheel wells covers on were missing on both sides of the trailer. The screws were simple sheet metal screws into the aluminum skirting on the bottom of the trailer.
The screws rattled loose from the road vibration over the course of 700 miles. A few more miles down the road and we would have been missing one or both of our wheel well covers, potentially damaging another vehicle on the road in the process.
Thankfully I had some similar screws in my tool collection. I tightened the remaining screws and installed new ones.
When we made it to our next overnight stop, I found a local ACE Hardware for new screws. Because the skirting is exposed to the weather and is made of aluminum, there is the potential to corrode cheaper screws. I went with stainless steel bolts, nylon washers, and lock nuts to eliminate the vibration issues.
When we are out of these 100°F areas, I will apply a bead of silicone sealer along the edge of the wheel well to add additional protection.
