We have a CYV and the washer/dryer are in the garage. I agree with some of the previous posters that having them there does free up space in the house and you hardly hear them when they are running. Temps inside the garage are not too bad in the winter or summer when you are there washing clothes. After all, you do not stay in the garage for a long time waiting for the cycle to finish
My only concern, because our villa is empty for most of the summer, is that the hi temps in the garage will dry out some of the rubber fittings which may cause an earlier than usual repair or replacement. I figure that fulltimers that use the appliances regularly, this should not be an issue.
