Creating bunk beds in a 171

As our kids have grown they've begun to complain about their room on the dinette at night.  It was time to give each of them their own bed.  I decided to add a bunk above the dinette.  I wanted to be sure I could still get to the storage under the seats, and maybe even remove it to use the table.  In the end I can get to the storage by lifting up on the front edge.  However, it ended up being a little too big to just remove as I hoped.  The tolerances are so tight I had to put one of the legs on with a ratchet through the front window, so no easy-out.  The towel is there to protect the wall and the front ledge.  It just sits on the ledge and the legs slip between the wall and cushions.  I made the bunk smaller than the dinette to leave a place to step up and a place to sit.
