Trailers ordered with the king bed option get a wider platform under the mattress.
We replaced our king OEM junk mattress as soon as we got the trailer. We installed a queen mattress like the one we sleep comfortably on at home, to avoid the extra cost and extra weight of a king mattress we didn't need.
The bed platform in our king-optioned trailer exceeds the width of our queen mattress by several inches on both sides.
Since you've decided to go with the king I'll guess that bed-making will be less of a pain than you're thinking it will be. Even with our queen we often slide the mattress down a couple of feet, make the bed, then slide it back up. Not a big deal.
Enjoy your new trailer!
This must be new because our 2019 came with our platform is not as wide as the RV king mattress we have.
