Class C regrets/Options you wish you had?First time class C

For me, I really can't think of anything I don't have in my 1975 American Clipper (21 ft class C) that I really need. Sometimes I think "I should get a generator" but then I realize that I haven't been in a situation yet where I needed one, so why get one. Other than that, there isn't anything that I would give up to gain something else.
