Look under portable washing machine in Amazon. Look at the Panda. It is 26x21.5x16.3
We bought one in Germany for our 2 month trip through Turkey in a rented motorhome, which is just a little smaller than the 24 Solera. It is light and only does a small amount at a time but sure beats doing laundry by hand. It was a real life safer on our overseas trip as there are very few laundries. We are thinking of one for our new Solera 24S.
