Why spend the "two bucks"? Wait to do it at home.
All kidding aside, we used to think the same way. But, we now full time in our motor home and love the washer and dryer. It cost us at least $10+- and 3+- hours every time we used to do a weekly wash. In the 3 years we've full timed, I don't remember a wash & dry for $2.00. They don't exist where we travel. Maybe a wash for $2.00 and then "line" dry".
We've got Ariston by Splendide stackable washer (ARWXF129W) and dryer (TVM63x).
Well worth it to us.
