Choose a washer dryer combo that is the right size for your RV. It should be large enough to wash and dry your clothes, but not too large that it takes up too much space.
Some washer dryer combos come with different features, such as a built-in lint trap or a self-cleaning cycle. Choose one that has the features you need.
Be sure to check the warranty on the washer dryer combo before you buy it. Some come with a limited warranty, while others have a full warranty. Choose one that has the coverage you need.
