Recommend a good Bunk Ladder

All the ones I've looked at, were on the order of extension ladders - little round rungs. My go-to for this is a hardware store step ladder. Modify to work. Maybe wooden. Easier to cut and you can staple carpet to the rungs. Last one I needed was a five-footer, unavailable in Big Box stores. Bought it at Ace. Our floor was carpeted. Between that, rubber feet on the ladder, and leaning against fabric, the ladder worked just as it came, leaning on the bunk closed.

Probably won't fit in your OEM space. I just left ours in the overhead bunk.
