The costs of doing something like this, would exceed the value of your trailer.
I have been on various hybrid forums for over 10 years and have never seen anyone do such a huge job on theirs.
You do see many that have the old pole supported bunks, asking if they can change them to the newer cable supported style.
Which isn't possible without changing the entire frame of the trailer.
so adding a slideout would be 10x harder.
