We normally use a pair of light-weight sleeping bags zipped together. In the morning we stuff them and the pillows into the left side dinette seat base which we reserve for that purpose. This system works, but has some deficiencies: 1) The light weight
bags tend to be too hot for warm weather and too cold for cold nights. 2) Even though they are light weight
they aren't easy to wash except in a very large capacity machine. 3) Since there are no sheets, the bags need to be washed frequently, in fact more frequently than we actually do. 4) In the evening during cold weather when they are removed from their stowage compartment, they are very cold to climb into.
I was thinking that someone must have developed a much better solution for those of us who don't have the convenience of leaving the bed made up. Or perhaps if several just tell how they do it, there will be several partial strategies that when combined will be the perfect solution of all of us!
