Laundry chute modification
One of the little features we like about our trailer is the laundry chute, which provides a way to dump you dirty clothes into a basket in the basement from the bathroom. However, I didn't much care for bending down to the floor to open it and close it, so modified it with a foot pedal and spring return. It actually turned out pretty well, see the photos.
