Since it is only my spouse and myself, I we use 2 Coughlin double bungee clothes lines (available at Camping World) rigged under the sleeping loft of our Scamp
19. That keeps anything drying out of any unexpected rain storms, and the double twisted bungee eliminates the need for clothespins. Provides more than enough space for towels and bathing suits. Had a bumper dryer I made out of aluminum probably 25 years ago but gave it to a fellow camper, as I like our current arrangement better. Works for us, anyway.
