Welcome to The Forum! I think converting a bunk room into storage is a great idea, and one I thought about doing myself. But I was looking at buying new, then converting, so it didn't make as much sense as it does for someone who already has the bunkhouse. In my research, I found that several people had included a small desk for a computer. If you spend some time "on line" (like those of us who follow this forum), that might be something you'd want to incorporate into your plans. Just a suggestion.
