New TTT plan: small push-out.

My first post. I have laid out a plan for a TTT that will be similar to a pickup slide in unit, without the cabover bunk.
This unit will sit on a 5x8 utility trailer. The trailer has 16inch side walls, and the unit will overhang the sides by about 1 foot each side.
As is, it will not comfortably sleep anyone. What I would like to do is build a 30" tall by 6' long "push out" to help with sleeping space. When extended, it will have two legs to help support any weight.
I attached my layout plan. I hope it is self explanatory. This is my first Tiny Travel Trailer attempt.
Now my question: does anyone have any experience making a push-out? Any sketches of construction technique?
