I hope you are going to put in nice handrails for the inevitable emergency rush to the toilet! Also, some padding on the ceiling above the bed will save you a few knots on your head, unless you were fortunate to have grown up with the lower section of the bunk bed like me. To this day, I always duck a little when I sit onto or off a bed. I know it's a little late, but have you though of having handrailings on the ceiling for getting to and off the bed and toilet? Maybe it's a bit of an athletic way to speed up going from the bed to the bathroom, but it's something I'd like in a space like that.
You may want to think about a cookbox or a pot cozy to be more efficient with your stove. Basically, it's an insulated container so that you can keep something warm instead of keeping it on simmer. It's not a permanent feature by any means, but you might as well experiment with it before you hit the road.
