I believe we bought it at a favorable price when Home Depot liquidated their "Expo" stores a few years ago. It is still available, and I've seen at OSH (a California home improvement store owned by Sears), and maybe even Home Depot or Lowes. I can't vouch for the price shown below, but I see it can be purchased from the DeLonghi store. Amazon may also have them.
It's the small DeLonghi shown here (on the left):

It works nicely in our 25-footer at the temperature ranges we tend travel in. There's no question that the larger versions would work better in colder temperatures, simply because there is a greater surface area to facillitate heat transfer (they both produce the same btu). The advantage/disadvantage pertains to size & weight versus heat transfer. The small one meets our needs, and it is often on low settings for a steady, even heat. If necessary, I put it on low on retiring in the evening to keep the coach from getting too cold. I can keep the living area warmer, and open the bedroom windows a tad for cooler, fresher air in that area. If you're consistently camping in 20 degree weather, or have a much larger coach, a larger heater may be better.
