TT mid bunk?

The why is easy for us. In every, or almost every rear bunk model the main "living" room feels like part of the kitchen. And usually only 1 sofa. And usually a double. In the few TT with 2 sofas you are watching the TV through the kitchen area. In the mid bunks, you get the full rear living area. This wouldn't be that important if we were just going camping on the weekends but we are going to be living in it. And my 20 year old daughter may be with us for a while. So we would like a bigger living room and a private room for my daughter. We are looking at fifth wheels but just wondering if there was a TT out there like that. TT's are a bit less expensive and require a smaller truck to tow.
