I have just completed installing mudflaps and wanted to share how that went.
I've noticed when towing in heavy rain there is a "rooster tail" of water spraying upwards from the tires which adds to what following cars encounter. There could be rocks and other debris flung in the direction of following traffic. Also I have been concerned that such debris might damage the black and grey water dump valves situated just behind the left wheel of the Rpod. To deal with such things I have installed some mudflaps.
The material used was salvaged from a truck mudflap I found laying along the highway. This mudflap is a thick rubberize material reinforced with heavy strands of nylon. I was able to use a heavy duty metal shears to cut two 11 X 12 inch sections for use as Rpod mudflaps. These were secured to the rear of the fenders using an aluminum strap and some stainless steel capscrews, washers and nuts. The following photo shows the right side mudflap.
The left side mudflap was attached similarly with attention given to making it short enough not to hit the blackwater dump valve. This is shown in the next two photos.
Above we see how the mudflap is short enough to miss the black water dump valve. It should reduce the chance of something flung from the tire striking the dump valves.
Above we can see the completed left side mudflap.
One thing I suggest with using stainless steel fasteners is to always use an anti-seize compound on the threads. If this is not done there can be galling and thread seizure or stripping. Stainless steel hardware is just too expensive to risk it being ruined in this way.
I've learned, at least in my maritime climate, that galvanized fasteners will soon rust and become unusable. While stainless steel is costly, it is cheaper in the long run. Also it works well in contact with aluminum, not being subject to galvanic corrosion. This could be a problem in areas where salt is used to deal with road ice. Stainless is the way to go.
