Hi Pam, I don't have the same layout as your trailer, but I have found that for home and for the Airstream a fitted sheet and a down duvet with a duvet cover work well. Down duvets work well in all temps (the range here is 100F to -40F). The covers come off easily for washing. Duvets are so light, you just fluff and let them settle nicely on the bed, so they are so easy to make...plus for the cost of a new cover, you can change your decor easily. Unless your bed is really in your way, I'd go for leaving it in sleeping position...always ready for a good nap! Here is a picture of my duvet cover. I used this for our first 2 summers. I was never in love with it, so this winter I bought a new, funky, 60s-inspired fabric cover. Can't wait to put it on in the spring!
