Anyone done a slide out from the back door?

Always have plenty of ideas for projects for my husband. My newest idea-has anyone ever made a small slide out that goes out the rear door of a cargo trailer?
I have a 6 x 10 with barn doors in the back. Looking to make more room inside. I usually have all my kitchen stuff in the rear, so I'm using it like a teardrop. Nothing fixed to the inside of the trailer.
My thought would be to just make a wooden box frame, with doors in the back and a small window on each side. Figured I could use Jacks to hold it up
when opened.
Thought today after checking out the Foamies, was even making something out of foam for the top and sides, wood for the floor we would be standing on.
Any ideas on how to make this easy for my husband? He already has a long "honey do" list.......
