I did buy the rail kit. It seemed expensive at the time but I am glad I bought it. If your hearth is elevated it makes it much easier to pull the stove to do the 1 ton cleaning. With out the rail kit I would either have to build something or have a second person, with some strength, to help remove the stove to get to the back during maintenance, which I do about 4 times per season.
Exactly what I needed to hear, thanks
