I don't know if this has been covered here before, but has anyone ever put a tankless water heater into a class A? This seems to make a lot of sense to me, and having put one in our shed for our kids waterslide before, I know they do not take up much space. Probably less space than a 6gallon Atwood. any thoughts? has anyone done this? I like to take showers in my own unit rather than the Canadian grounds when we go fishing, and we take turns with the 6 gallon one now.
