Hi Again Joe,
Well, I wish all the projects I start ended that easily. I called Casita
and they said there were 2 screws that hold the panel between the bed and small table (actually there were 4). One is in the cupboard above the table and the other 3 in the wheelwell below the table seat, all on the table side. I took those out, sprayed a bit of good old WD40 on both sides of the divider to get it to move easier, wedged my crowbar (covered in cloth) between the trailer wall and the divider, and it popped out! Now we will build some kind of slide out like you did for the mattress, and a cap for the end of the cupboard above the bed.
Thanks much for the ideas and encouragement!
