I'd leave that as it is until you have a serious buyer or cash in hand preferably.
Next you have to have a plan for the hole in the roof before removing the stove and pipe.
Not sure what you have for flooring but that will be heavy even when taken apart. You don't want gouges or scrapes, dents in the floor do you?
Whoever lifts it out should be protective of this but that will be up to you.
That's a nice install, better than most installs I see done.
It adds more potential to the vehicle if you should ever sell, to have a safe stove that actually works.
But everyone has their own reasons, good luck with this sale.
