The thing about the Argos bunk is it’s only a normal double that’s 6’3″ long. Liv tested a few beds out at the bed bunker and that size doesn’t allow you to stretch out properly. A 6’6″ King size definitely permits a more comfortable lie, the more so the taller you are. As it happens, the DD is 6’6″ long. So, take your pick … all I would say is that by the time I’ve finished the reconstruction, in craftsmanship terms, you would hardly be able to tell the difference.
