New sofa modification for extra storage

Here is a quick modification that I did to Penelope today so that we could have a space where the kids could keep toys.  They will each get a bin under the sofa that will contain their own special stuff.  This really is an easy modification to do to any motor home.  It took me about 20 minutes to complete and gave us approximately 6' x 3' deep of extra space to store things.  It was accomplished using some leftover 1x material and 2 regular door hinges, 8 wood screws and 6 multimate screws to get into metal.  I had to have an extra set of hands when it came to the final attaching.
