Well I finally found time to do the ladder mod I mentioned before. Turned out pretty well although my wife pointed out that it should have been against the other wall. She is probably right
We haven't tested it out yet and that will probably have to wait until next season but the girls had lots of fun climbing up and down it while I was trying to build it. The biggest, obvious, drawback is the lost bed space but both our girls are short so we have a few years at least until that is a problem.
The mod is pretty easy and no real permanent alterations needed to happen.
The girls are going to love this next year!
