Extending teardrop floor pass the trailer frame.

Hi all,
Before I was approved for the forum, I stumbled on a post where a member showed pictures of how he extended his floor (width) beyond the trailer frame and over the wheels. I believe he also had a sunken floor where he was going to install a VW folding seat frame for his bed. Can you help me find this posts and pictures. I would like to take advantage of the lessons learned and apply some of his techniques. I will not be putting in a folding seat/bed, but I feel a need for a hidden vault. Thanks.
