Never thought I'd be asking this question, but ... Sheets?

but a couple sets of these.

I like my custom sheets in the RV. Can get the flat sheet extra long to be sure it tucks in a little extra as you like. Or extra wide if sharing is an issue. Then I would be getting the suspenders/keepers if needed.

+1 for Costco if the mattress is an exact fit standard size.

The Charisma brand sheets from Costco work great on the king size bed in the camper.

We have fitted sheets for deep mattresses (queen) which work great. Mom found them on Amazon.

There are fitted sheets for thicker mattresses. Might work better.

I have found California King sheets fit the best, with no straps or mods.

We have an egg crate pad under the mattress so it doesn’t slip on the pedestal.
Maybe that traps the sheet corners??

We use sheet suspenders as well for our "RV queen" mattress fitted with standard queen sheets. We found the three way style works best for us.

Use these, also, but got mine at Wally World for about $4/set. I have two sets on the RV King.

We got one of those non-skid pads meant to place under an area rug and placed it under the mattress. It does 2 things... keeps the mattress from sliding down the slippery wooden platform it sits on, and it also helps hold the fitted sheet in place.
