I do the towel thing, too. The one made by Camco actually had some rubber stuff on the back so it would stay without sliding.
One of my nephew's moms said her partner wanted to buy a motorhome but didn't want one with any rattles because she cannot stand to drive with rattles. Told her there was no such thing! Glad Winnebago got this right, though.
I bumped into one of the electrical engineers for Fleetwood in the parts building. I told him I would be happy to participate in any focus groups they had for women drivers of RVs. I pointed out to him that I was 5'1" and could not reach the ceiling lights without standing on my toes and hopping up and down, and that they needed wall switches for short folks like me or children. He said they put wall switches in the Class As, but always assume people in cheaper models (Class Cs) could get a stool, but he admitted that dragging around a stool was not very convenient. I told him stools were also tripping hazards. Glad to get my 2 cents in anyway.
