Don't have a 37K, where is your closest 120V outlet? I would suspect you have one in the slide out, as Jayco has been making a point to have power points at all sleeping locations for CPAP machines.
From Jayco's 360 degree view, it looks like you have one under the dinette bench against the sofa. Could install a romex wire along the carpet line in a wire mold (aka plug mold). It would be hard to see. If you want something a little nicer looking install a piece of molding over it, and paint it appropriately.
Let us know what you do and how you did it
