RV sheets

I imagine you can find the right size sheets with the suggestions above. But have you tried all the different kinds of bed sheet straps? I was surprised when I just searched the internet, there were about half dozen kind that all worked differently. Other than the basic strap, one was a triangle strap with three connection points at the corners. Another actually went under the bed all around. Another was a group of L shape plastic thingies that tucked under the bed and attached to the sheet at several points. I would think one of these would work sufficiently. Heck, I may order something myself now that you brought up the subject :)
