These look new or maybe I'm just now discovering them...

Solitude 320X http://www.granddesignrv.com/solitude-floorplans.php (No specs on this one yet)
and

Reflection 27RL http://www.granddesignrv.com/reflection-floorplans.php (This one looks to be around 30ft and under 8k in dry weight) I know several people have expressed an interest in this length and weight for a 5th wheeler.
