We would like to get an RV furnace, but how do I know what size we need?
Our bus is 31' long, so imagine about 28 feet long inside.
There are several listed in the Craigslist for our area, one is a 24k btu, another is 16k btu. Which would work well for us? The 16k is much, much cheaper.
But it's all for naught if it doesn't heat the bus properly.
