The cupboards should have come with shelves. Because the doors are smaller than the cabinets it's pretty much impossible to add standard full-width shelves. I build some self supporting shelves (think of an upside down U) to help add storage space.
" The lack of drawers is a challenge" Yes, it is. That's why I and several other members built a drawer where Coachmen should have put one.
I wrote up some instructions on how I went about building mine.
