You have a very nice listing and I love the story and ambiance and the way you have presented it.
Maybe use The Outpost in the title?
Just a few thoughts of mine as I read the listing.
If you are hosting for the first time, I would not use instant book to start. You will need to vet your guests to avoid partiers or more people than you want. When you mention parking for 4 cars plus, and chairs that turn into beds you may attract the wrong crowd. Or maybe not, you know your market. 🙂 6 guests is plenty.
There is an inconsistency with pets- description says dogs welcome but house rules say no pets. Along the same lines, think about wildlife possibly clashing with a guests dog, it might be worth a warning if there are coyotes or wolves around.
I agree that the exterior should have a bench or seating area staged. Even if you are not going to use it in winter, it makes an inviting photo.
I wouldn't say that you are rarely in town. Again might attract the wrong crowd.
One last tip if you are new at this, and even if you are not, with a whole house do not try and do a same day turn-around. At least one day between will allow for those big cleaning jobs and unexpected repairs etc.
Cheers and best of luck!
