Congrats on the new rig! If you know the size of the king bed, you have all the info you need. If it's shorter than standard, Camping World sells sheets that will fit.
We have a short queen, and still use regular queen sheets from Wal-Mart. They are a bit bulky, but not much, and that can be solved by using a couple of sets of the sheet holders (I don't know what they're called) to take up the slack under the bed. Problem solved. That way you can use off-the-rack sheets.
There are vendors who specialize in sheets and bedding for RV's. Just do a search for it. Lots of options for colors and designs. Fitted for your size mattress.
Thanks - have the answer. We were trying to find split sheets for the bed - do not need split sheets.
I was confused and thought the bed was like a temperpedic with separate sides that raised. While it has separate controls for each side the bed raises as a unit to king sheets will work fine.
Thanks for the help and pardon my confusion.

Our '13 Tour QD has standard sized King Sheets. We have been using the same sheets as in our Sticks&Bricks house. But, we are less than 3 months from full-timing with our existing King Sheets. We're very excited (in case you couldn't tell).
Enjoy your new ride...and, get all the little bugs fixed within the first 12 months.
