Also known as don't lean on the back wall. No really, don't lean on it.
We had a full weekend, Friday night arrived at hotel and kids went swimming. Saturday we worked on cabin. Finished pulling old wood and 8 million freaking nails out of the studs in the back wall.
Pulled out the old "framing" and put in the window frame as designed. Spent time re-attaching the back wall to the new frame to help solidify it.

The windows only need to be purchased and can be installed in the back wall.
