yep we hang out at the Ocean a lot and all the salt air and rain makes rust on the bottom plate quick so I started spraying WD-40 on the bottom plate to keep it at bay,when I had my Old 2004 Big Sky it came with a cover I thought was for the Pin Box and it fit almost perfect,then someone at the resort one day said Hey nice use for a Hitch cover.....OOPPSSS whatever works
So anyway I was going to buy another 5th wheel hitch cover from Amazon because they fit pretty well on the pin box I am tired of putting WD-40 on my plate and top of the box to keep away rust
