Sue,
I take off the sheets and bring them in the house. When we get ready to go again, I wash them (again) so that they will be fresh smelling.
The mattress pad and topper stay on the Coach.
We carry two sets of sheets when we are on the road in the summer. Regular and flannel. Last year when we were in NH, we really needed the flannel sheets. Actually, if I remember correctly, I needed them last January at Franklin Locks--Florida--Who Knew!
