OK, Washer and Dryer in your RV...Do you use them?

I think the difference in wanting-having-needing a washer/dryer is the length of stay in your camper. The shorter the stay, the less you really need one inside the camper, when you are always returning home after a day or two.

Longer trips, in excess of 2 weeks to 30 years is another matter. It's all a matter of your own convenience (and how many quarters you can acquire between wash days, and how much time you don't mind waiting in a laundry mat - campground or other.)
