My bmbh is almost perfect. Only one problem. I am 6 foot 3 and so is the hammock. I bump both ends and if I slide any at all it becomes annoying.

Adding a 6 inch foot box and or a head box would give comfort for taller
hangers and more storage space for everyone.

It should be an easy modification for JRB to do. I might try to do it myself.
If I can get the nerve to cut into the end panel.
