camping with kids

I have yet to be inside a 3023, but it is one we are looking at (the other being the 2720). We are wondering if the couch/bed could be extended to make a bed such as the dinette bed in the 2720? The brochure says the 3023 can sleep 6, but that means 2 people have to sleep on the 41X69 couch! It could be done, but not comfortably! Just wondered if it was possible, or if anyone had made this modification?
Thanks!
