Cleaning Camper Trailer

I'm so "fortunately" a very strong and cold. For that I must, however, since Sunday schlafenXD here is so great.
Unfortunately, I did not upload photos, I try tomorrow or so.
Anyway .. I think I've changed my mind pretty extreme. What "things" are concerned.
I feel so comfortable here. Although it is only a week ago, but ..
Can anyone explain this feeling of butterflies in your stomach?
