We LOVE our 28BHBE. As far as weight goes, IIRC the Flight has more CCC than the WhiteHawk, so while the "dry" weights are similar, the GVWR is higher on the Flight (?). Also, the Flight is taller than the WhiteHawk inside which is nice. But from a functional floor plan and usage standpoint, they are not that much different IMO.
Very nice shower too, that was one of the main selling points along with the configuration of the bunkhouse and the space created by the huge slide.
As far as the dinette, Jace817 said the living space isn't great for TV watching, and I would have to agree. What I do is remove the table from the dinette and slide it in between the couch and the back of the dinette. This creates a nice "lounge" area and I can kick my feet up and relax while DW lounges on the couch. I'm planning to make a small "cocktail" table to put in there when I have it set up this way so I have a convenient place to set my "beverage".
