When I lived in a trailer, I didn't take mixing or serving bowls at all, only used four pyrex measuring cups: 1 cup, 2 cups, 4 cups and 8 cups. They served many purposes and fit easily. Now I have many serving and mixing bowls, but those four pyrex measuring "cups" are ones I always recommend to folk starting their first kitchen.
Three friends of mine and I own "community" stuff (carpet cleaner, car top carrier, roto-tiller). Now, another friend and I are going to "co-own" a stand mixer. Sometimes, co-owning stuff is the way to go. The person wanting to use it, has to go and get it and bring it back. I also share my serger with a friend in exchange for her pressure washer.
