Best of luck to you on the next phase of your life. We were not full timers, but life circumstances led us to sell ours last year after 14 years of traveling in it. Loved every minute of it.
I listed ours on Facebook Marketplace on a Wednesday. Got 1st inquiry next day with a commitment to view it on Friday. Lady saw it and said she wanted it but her husband couldn’t see it until Saturday. He committed to buy on Saturday. Met her at her bank on Tuesday and got a bank check for full amount. 20+ more inquiries before I could mark it sold on Marketplace. Quick, easy, and safe with the bank issued check. With Marketplace you can limit the ad radius to make it easy for potential buyers to come see it.
And obviously I haven’t stopped hanging around the forum.
Used F350s are drawing a premium right now. You will not have a problem selling that either. Of course you will pay a premium to buy something else.
