Your information may be flawed. From doing a bit of research on the net it seems to me that the 2009 HW276 came with a fixed-in-place interior 3 burner stove w/oven. An RVQue grill went on the outside. If you are interested in an outside stove, the 1640 and 1940 Freedom/LTD models come with a two burner stove that can be removed from the inside and hooked up outside. I would presume there is some way to hang it from the side of the trailer. Maybe you can purchase one, and the appropriate hardware, from FR. Check out the popup page on their site.
