Location: Valentine, NE USA | Well - I went ahead and opted to just get 2 treated 2x4's and some good, heavy outdoor carpeting.
The water retention in the carpet COULD be caused by air space between the carpeting and the boards. Some of the heavier carpets, like mine, were a *^%$ to get tight on the boards. I went through 150 screws to get mine as tight as I could. Still ended up with a a few air pockets here and there but...
Just look at the ends of the boards, if you can see them, if they're starting to split or look rotten...it's time for new bunk boards.
