That's an excellent suggestion - depending upon the interior design of your RV - including whether or not your propane furnace has multi-ducted outlets with their tubes running along inside various cabinet voids.
That setup would work like a champ inside our Class C ... making allowance for the fact that during very cold weather drycamping the extra fan(s) will draw current in addition to the propane furnace's already heavy current draw whenever the furnace was running. (Plus, in our case, the grey & black electric tank heaters would also be drawing heavy current, too.) It would be nice if the Fan-Tastic Vent company would offer an "Endless Breeze" type fan especially for the use you suggest, as it would probably draw less current than the one you show in your photo.
As far as I can estimate, extreme cold weather RV living is going to require hookups or a lot of daily generator running.
