Clothing washing machine Only problem with a stack is that you can't run them both without lots of available power.... and you can't see into the washer worth a hoot unless it's a front loader. When we boondock it's a real blessing to be able to do a load now and then and not have to search out a coin laundry. It's also nice to know someone has not just washed greasy coveralls in the machine before you use it. People use coin laundrys to wash things that they would never wash at home. Big sign over as campground laundry in Florida "This machine stains cloths"... just more stuff we don't have to put up with.
