Inventive ITD9187LR RV Fender Skirt and Mud Flap (Lr Universal Fits All 2.5In X 2.5In Receivers)

Very disappointed with the seller of this item. The mud flaps themselves are nice. As was previously posted the "shank" wobbles, it is annoying at best and MAY contribute to the mudflaps falling off.My main complaint is that we installed these mudflaps using the bolt/nuts provided and following the straightforward instructions. They were tightened well. We went for an in town errand and arrived to find one mudflap was missing and the other was held on by only one loose bolt (the nut had already worked off). Obviously, we took the remaining mudflap off and continued with errands.I contacted the seller to see about getting a replacement mudflap. After about three weeks of back and forth emails, they asked for pictures of the missing mudflap and the other hanging on by one bolt. Seriously, after I had explained multiple times that I did not stop to take a picture at the time, and I surely do not have the mud flap hanging on by one bolt, they stopped communicating with me.I want a replacement mudflap and mounting plate that was lost. Apparently, this design is only sold in a set, as I found the same in a tractor store but they would not break up a set to sell a single flap.The mudflaps are heavy and nice. We really would like a mudflap so we can use them. If you do buy them, expect to use longer bolts. Also, use a locking nut and liquid lock tight. I do not know if it is the vibration from the wobbly shank that contributes to the nuts working themselves off.If you do purchase these, and find you are missing a mudflap, be sure to take a lot of pictures and expect the seller to question your ability to screw a bolt into a nut.
