Hi Road Less Traveled, it is nice to see another sharing about the lifestyle you and I share. I have been writing about extended stays and fulltiming for a number of years now and enjoy helping others trying this too. For what I have read, so far, is very familiar in many ways. Of course I wouldn't know what to do with all of the space of a 5th Wheel, being in a Truck Camper myself. I am always enjoying reading how others are being successful on the road (read, stealing ideas!) and will look forward to seeing your future posts.
Wave style heaters are great, up to a point. They can be too warm when outside temperatures get above 55*F and are unable to keep up when outside temperatures are below 25*F. Being able to moderate by opening windows and turning on a furnace is important, for extended summer camping or 4 season camping. Just know the limitations of both Wave Heaters and Furnaces and one will be fine.
Hope to see you posting more often here and the best to you and safe travels!
