I wanted to have easier access to the storage area under the bunk bed in my 174bh. So I removed the panel without having to cut/modify or damage it. I am able to pull it out and slide it back in for a tight fit!
3rd pic is the final product.
I plan to add a turn button or something soon. It sits in there pretty tight, especially on the left side where it's actually sandwiched between the wall and the bed framing.
