It's hard to find the sheets to fit the bunks in the Independence. The mattresses are longer and more narrow than a standard single or even the long single size. Many order custom made sheets, or sew them themselves.
It turns out that the size or our bunks is apparently very similar to what some truckers need in their big rigs. I went to a truckers supply website and found them at a reasonable cost.
For the blankets and bedspread, I just cut queen size blanket and bedspread in half and finished the cut edge.
