Just as an aside....the 70X80 "RV King" in your master bedroom is neither a King or a Queen. We fought both sheet sizes in the past try to make them work.
We finally purchased a real Queen mattress. I made the proper cuts to the platform. No more fighting sheets that are too big or too small. :
PS The "RV Sheets" at Camping World, are NOT RV (size) Sheets.
