We upgraded our mattress out of a 2020 Jayco.this mattress is in as new condition we just needed something firmer . Replacement is about $1,500.00 from Big Boys Toys . Will obviously fit any RV that takes an RV King . This mattress has a fold in it as the beds in the slide . Mattress is 68" wide x 80" long . Want it gone by the end of the weekend. Let me know, thx
