I have a '74 Argosy stored out in the country near here -- the interior decor is a mix of Boeing 707 and go-go dancer colors. I don't know if I can point to any particular member gallery here -- some stick with original, some accessorize along a theme, and others redecorate and change colors, partitions, etc. I saw one of my favorites at a rally last summer but that member has not posted pics anywhere that I know.
There is a big issue of adding too much weight if you gut the interior. I don't know exactly what you're looking to do.
