I'm not 6'3" but at 5'11" our new White Hawk is tall enough. Older White Hawks have some kind of sandwich flooring to keep the weight down but ours is solid plywood, and sturdy. We haven't even begun to fill all the storage in our 28DSBH. There is a large storage under the bunk and the forward pass-through is cavernous compared to our last TT... a Surveyor. To me the stick and tin days are over. The structure of the aluminum frame, block foam, and everything bonded together is far superior, both in strength and insulation quality... But then I'm an aircraft guy. My glider was built with that kind of structure.
We're just back from our second trip and we took our grand daughter along. The top bunk is hers, and hers alone... If you don't believe it, just ask her!
