Many retailers have moved away from selling Propane. There are new regulations every couple of years that generally involve either new equipment or relocating the tanks and fueling area. It isn't very profitable to begin with if you want to be price competitive and when you add in the labor it just doesn't make financial sense. On top of that, many RV propane fill connections range from either very difficult to access to a location that would challenge a Cirque Du Soleil acrobat. I threw in the towel when I crawled under a VW campervan in a 35 degree rainstorm to put in exactly 3/10s of one gallon of propane all for a whopping 75 cents. I don't envy those retailers at all.
