20" matress in a 24' 5th wheel?

Hi! New to the forum, new to rv living. Laugh all you want I deserve it. I bought a 20" deep queen matress. Then I bought a 24’ forest river . What are my chances I can get the bed into the rv?

Oh my. Good luck. I once had a 27 foot 5th wheel with a queen size matterss. There was no way of getting that thing out of there. They put the mattress in before the roof went on. If you do get it in there, I’d like to know how. Good luck!
