We generally spend 3 to 4 months per year in our Excel, with a long trip being 5 to 6 weeks at a time. We tried to go without a washer for a while when we had the motorhome but the wife did not like the way some of the coin operated machines treated her clothes so we got a Splendide. It has become indispensable especially on our longer trips. She is not tied to a laundromat for however long that takes and can do other things while the washer does its thing. What I am trying to say is the need for one depends on how you use your rv and how you want to budget your time. I know some folks who like using the rv park's machines because they like meeting people. I guess it all depends on how you look at it.
