Dave,
we have one like the other message showed, a granny, purchased
at ace hardware. not likely to help you for beer and such, since there's
no ace or home depot or such around.
we also have a fold up dolly/dock cart as in west marine. maybe since
you're in the VI's you could ship it in. may be able to get one at
island water world or that other chandlery by frenchtown.
