nice work.
i've made a couple, and they started
nice but got too complicated and full
and heavy. i wouldn't add anything
more than you have. before you know
what happened it's full of stuff you
never use or need and you get to where
you hate to see it because you know you'll
have to wag the heavy thing.
another drawback is if you camp with others
around as in a public campground or on public
land at a designated campground that chuckbox
is a an eye magnet for everyone else that
needs salt, pepper, paper plates, an extra fork,
etc. , or maybe even looking to pick their selves
a new chuckbox when nobody's looking
a tip i can give you from camping on public land
and hunting for a lot of years is to put your name
on every last piece of gear you have. i even put
my name on all my silverware i had for camping
with an electric engraver. if your cooler or waterjugs
come up gone, and there's 35 people there, there's
no way for the warden or deputy to identify your
gear from someone else's. i have lost a few things
from someone's greed.
good luck with it and have fun
