While it seems that a 6-8 inch floor sticking out does not seem to bother most folks shins. I did not like the idea of losing that much space out of a 4'x8' floor. So here is what I did and I ended up with a lot more counter space with folding tables on the outer doors.
This picture only shows table on the right side. I have since put one on the left.
Here is a not to great pic of them both on and deployed. I usually put the coleman camp stove on the right side.
I ended up losing less than 2 inches of floor and it still left plenty of room for the stowed away tables and mechanicals for the outer door latches. Not a very elegant profile I will have to admit. A curved hatch would help.
Not for everybody but it works for me and build #2 will be similar.
